How Sound Wave Travels – Basic Physics?
 
05:46
Visit: http://www.expertsmind.com :- How Sound Travels? In a liquid or gas, sound consists of compression waves. In solids, waves travels as two different types. A longitudinal wave is related with compression and decompression in the direction of travel, which is the similar process as all sound waves in liquids and gases. It is explained with simple example.

Bolt [ [Massachusetts Institute of Technology, Bolt, Beranek and Newman, BBN Technologies] discusses sound wave phenomena, how sound travels, and how it is reflected. The film demonstrates that sound is a wave phenomenon and thus can also move around barriers. Also the film shows how sound waves can be refracted through a lens." Public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). https://en.wikipedia.org/wiki/Sound Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a transmission medium such as air or water. In physiology and psychology, sound is the reception of such waves and their perception by the brain. Humans can hear sound waves with frequencies between about 20 Hz and 20 kHz. Sound above 20 kHz is ultrasound and below 20 Hz is infrasound. Other animals have different hearing ranges... Sound is transmitted through gases, plasma, and liquids as longitudinal waves, also called compression waves. It requires a medium to propagate. Through solids, however, it can be transmitted as both longitudinal waves and transverse waves. Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure, causing local regions of compression and rarefaction, while transverse waves (in solids) are waves of alternating shear stress at right angle to the direction of propagation. Sound waves may be "viewed" using parabolic mirrors and objects that produce sound. The energy carried by an oscillating sound wave converts back and forth between the potential energy of the extra compression (in case of longitudinal waves) or lateral displacement strain (in case of transverse waves) of the matter, and the kinetic energy of the displacement velocity of particles of the medium... https://en.wikipedia.org/wiki/Wave In physics, a wave is an oscillation accompanied by a transfer of energy that travels through a medium (space or mass). Frequency refers to the addition of time. Wave motion transfers energy from one point to another, which displace particles of the transmission medium–that is, with little or no associated mass transport. Waves consist, instead, of oscillations or vibrations (of a physical quantity), around almost fixed locations. A wave is a disturbance that transfers energy through matter or space There are two main types of waves. Mechanical waves propagate through a medium, and the substance of this medium is deformed. Restoring forces then reverse the deformation. For example, sound waves propagate via air molecules colliding with their neighbors. When the molecules collide, they also bounce away from each other (a restoring force). This keeps the molecules from continuing to travel in the direction of the wave. The second main type, electromagnetic waves, do not require a medium. Instead, they consist of periodic oscillations of electrical and magnetic fields originally generated by charged particles, and can therefore travel through a vacuum. These types vary in wavelength, and include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays. Waves are described by a wave equation which sets out how the disturbance proceeds over time. The mathematical form of this equation varies depending on the type of wave. Further, the behavior of particles in quantum mechanics are described by waves. In addition, gravitational waves also travel through space, which are a result of a vibration or movement in gravitational fields. A wave can be transverse, where a disturbance creates oscillations that are perpendicular to the propagation of energy transfer, or longitudinal: the oscillations are parallel to the direction of energy propagation. While mechanical waves can be both transverse and longitudinal, all electromagnetic waves are transverse in free space...

Public domain film from the Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://creativecommons.org/licenses/by-sa/3.0/ http://en.wikipedia.org/wiki/Sound Sound is a mechanical wave that is an oscillation of pressure transmitted through some medium (like air or water), composed of frequencies within the range of hearing... Propagation of sound Sound is a sequence of waves of pressure that propagates through compressible media such as air or water. (Sound can propagate through solids as well, but there are additional modes of propagation). Sound that is perceptible by humans has frequencies from about 20 Hz to 20,000 Hz. In air at standard temperature and pressure, the corresponding wavelengths of sound waves range from 17 m to 17 mm. During propagation, waves can be reflected, refracted, or attenuated by the medium. The behavior of sound propagation is generally affected by three things: - A relationship between density and pressure. This relationship, affected by temperature, determines the speed of sound within the medium. - The propagation is also affected by the motion of the medium itself. For example, sound moving through wind. Independent of the motion of sound through the medium, if the medium is moving, the sound is further transported. - The viscosity of the medium also affects the motion of sound waves. It determines the rate at which sound is attenuated. For many media, such as air or water, attenuation due to viscosity is negligible. When sound is moving through a medium that does not have constant physical properties, it may be refracted (either dispersed or focused). The mechanical vibrations that can be interpreted as sound are able to travel through all forms of matter: gases, liquids, solids, and plasmas. The matter that supports the sound is called the medium. Sound cannot travel through a vacuum. Longitudinal and transverse waves Sound is transmitted through gases, plasma, and liquids as longitudinal waves, also called compression waves. Through solids, however, it can be transmitted as both longitudinal waves and transverse waves. Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure, causing local regions of compression and rarefaction, while transverse waves (in solids) are waves of alternating shear stress at right angle to the direction of propagation. Matter in the medium is periodically displaced by a sound wave, and thus oscillates. The energy carried by the sound wave converts back and forth between the potential energy of the extra compression (in case of longitudinal waves) or lateral displacement strain (in case of transverse waves) of the matter and the kinetic energy of the oscillations of the medium. Sound wave properties and characteristics Sound waves are often simplified to a description in terms of sinusoidal plane waves, which are characterized by these generic properties: - Frequency, or its inverse, the period - Wavelength - Wavenumber - Amplitude - Sound pressure - Sound intensity - Speed of sound - Direction Sometimes speed and direction are combined as a velocity vector; wavenumber and direction are combined as a wave vector. Transverse waves, also known as shear waves, have the additional property, polarization, and are not a characteristic of sound waves... Perception of sound The perception of sound in any organism is limited to a certain range of frequencies. For humans, hearing is normally limited to frequencies between about 20 Hz and 20,000 Hz (20 kHz), although these limits are not definite. The upper limit generally decreases with age. Other species have a different range of hearing. For example, dogs can perceive vibrations higher than 20 kHz, but are deaf to anything below 40 Hz...

Sound Wave Telephone Experiment
 
01:03
As a part of our Sound Exploration Unit, students at CPE II are learning all about sounds. This past week students from some classes engaged in an activity designed to teach them how sounds travel from one end to another. This activity served to reinforce concepts of how sound waves are created and how they travel through air. With the help of a long string, two plastic cups, and two paper clips, students learned how to create a working telephone. The Science Behind the Activity As a student speaks into the cup, the bottom of the cup vibrates. (Sounds are created by vibrating objects.) A vibrating object moves back and forth. As it moves forward, it pushes against the air around it, compressing or squashing it. As it moves backward, it lets the air spread out. These squashing and expanding movements create a sound wave. The vibrations also travel through the string. The person who receives the message can hear the sound waves created by the person who sends the message.

How the ear works
 
03:26
You may license this video royalty free by contacting us at http://www.javitz3d.com Many of us take for granted a very extraordinary ogan... our ears. To understand the ear, we need to understand what sound is. The speakers you are listening to right now are vibrating...flexing in and out causing a wave of pressure through the air The frequency of these waves, or the speed at which the sound creating surface moves back and forth affects the pitch of the sound. The level of air pressure in each wave is directly related to how loud the sound is. The outer part of our ear catches these waves. It faces forward and has a specially designed structure of curves helping us to determine the direction of sound, and emphasize frequencies used in human speech Now that the sound waves are caught, they travel through the ear canal and strike against our eardrum...a thin membrane about 10 mm wide. Now that we received the sound, the middle ear transfers this energy. The smallest bones in your body, the Malleus, Incus, and Stapes start in motion. The Malleus is attached to the eardrum, and as the sound travels along the force is amplified by leverage until it arrives at the Stapes which acts like a reverse piston creating waves in the fluid of the inner ear. The most significant increase in pressure is caused by pneumatic amplification. The face of the stapes has a surface area of 3.2 square mm, while the eardrum has a surface area of 55 square mm. Using this, along with leverage through the Malleus and Incus, the final pressure is 22 times greater than when the sound first arrived. Now we come to the most complicated part of hearing... the Cochlea. In reality, it is coiled up, but it is easyer to understand straightned out. There are actually three chambers inside, but lets take a look at the central part. The stapes is cuasing pressure waves to travel through the structure. Along the inside wall is about 20-30k reed like fibers. As the waves move along they encounter fibers with the correct resonant frequency and energy is released. These fibers aren't actually what give us the signal that we heard something. There is a special structure next to these fibers containing hair cells. When the hair fibers resonate, they cause the hair cells to move, which then sends an electrical impulse to the cochlear nerve, and on to the brain. Certain pitches of sound will resonate in specific locations, and louder sounds will cause more hair cells to move. Our brain interprets all this raw data, making it possible to enjoy things like music, or an engaging conversation. Just to think that all of this is happening in your head right now at full speed. And not just one, but two of these sophisticated instruments are giving you the amazing sense of hearing. This is just one of the amazing systems found in the human body that go far beyond our humble human understanding.

Sound waves cause changes in air pressure as particles bunch together and spread apart. Now, we can’t see these ripples but our ears can hear them. When the waves reach our ears, the air pressure goes up-and-down and this makes our eardrums go in-and-out at the same rate. Our brain analyses these signals and interprets them as sound.

Electromagnetic Spectrum: Radio Waves
 
03:58
http://www.facebook.com/ScienceReason ... [email protected]: EMS Electromagnetic Spectrum (Episode 2) - Radio Waves The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. The "electromagnetic spectrum" of an object is the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. --- Please SUBSCRIBE to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker --- MEASURING THE ELECTROMAGNETIC SPECTRUM The electromagnetic (EM) spectrum is just a name that scientists give a bunch of types of radiation when they want to talk about them as a group. Radiation is energy that travels and spreads out as it goes - visible light that comes from a lamp in your house and radio waves that come from a radio station are two types of electromagnetic radiation. Other examples of EM radiation are microwaves, infrared and ultraviolet light, X-rays and gamma-rays. Hotter, more energetic objects and events create higher energy radiation than cool objects. Only extremely hot objects or particles moving at very high velocities can create high-energy radiation like X-rays and gamma-rays. • http://imagine.gsfc.nasa.gov/docs/science/know_l1/emspectrum.html --- RADIO WAVES Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Like all other electromagnetic waves, they travel at the speed of light. Naturally-occurring radio waves are made by lightning, or by astronomical objects. Artificially-generated radio waves are used for fixed and mobile radio communication, broadcasting, radar and other navigation systems, satellite communication, computer networks and innumerable other applications. Different frequencies of radio waves have different propagation characteristics in the Earth's atmosphere; long waves may cover a part of the Earth very consistently, shorter waves can reflect off the ionosphere and travel around the world, and much shorter wavelengths bend or reflect very little and travel on a line of sight. Discovery and utilization: Radio waves were first predicted by mathematical work done in 1865 by James Clerk Maxwell. Maxwell noticed wavelike properties of light and similarities in electrical and magnetic observations. He then proposed equations, that described light waves and radio waves as waves of electromagnetism that travel in space. In 1887, Heinrich Hertz demonstrated the reality of Maxwell's electromagnetic waves by experimentally generating radio waves in his laboratory. Many inventions followed, making practical the use of radio waves to transfer information through space. Propagation: The study of electromagnetic phenomena such as reflection, refraction, polarization, diffraction and absorption is of critical importance in the study of how radio waves move in free space and over the surface of the Earth. Different frequencies experience different combinations of these phenomena in the Earth's atmosphere, making certain radio bands more useful for specific purposes than others. Radio communication: In order to receive radio signals, for instance from AM/FM radio stations, a radio antenna must be used. However, since the antenna will pick up thousands of radio signals at a time, a radio tuner is necessary to tune in to a particular frequency (or frequency range). This is typically done via a resonator (in its simplest form, a circuit with a capacitor and an inductor). The resonator is configured to resonate at a particular frequency (or frequency band), thus amplifying sine waves at that radio frequency, while ignoring other sine waves. Usually, either the inductor or the capacitor of the resonator is adjustable, allowing the user to change the frequency at which it resonates. In medicine: Radio frequency (RF) energy has been used in medical treatments for over 75 years generally for minimally invasive surgeries and coagulation, including the treatment of sleep apnea. • http://en.wikipedia.org/wiki/Radio_waves .

Sometimes the earth is so noisy... roads, aeroplanes, volcanoes, construction work... but have you ever thought about how noisy it must be underwater, for the poor marine life that cannot escape? What if I told you that sounds underwater are even louder than they are above water? Particles in water are closer together than air particles. Not only is the noise irritating and unpleasant for marine life, a lot of animals use sounds and echolocation as their main form of communication. Sound travels over four times faster than in water, which means who whales can potentially speak to each other anywhere on earth! How crazy is that! Humans have definitely contributed to ocean noise, and so what can we do to reduce some of it? Buy local produce, then there will be less shipping.

How Hearing Works Video - Process of Hearing Animation. Function & Parts of Human Ear. Sound Pathway
 
01:38
As sound waves enter the ear, they travel through the outer ear, the external auditory canal, and strike the eardrum causing it to vibrate. The central part of the eardrum is connected to a small bone of the middle ear called the malleus (hammer). As the malleus vibrates, it transmits the sound vibrations to the other two small bones or ossicles of the middle ear, the incus and stapes. As the stapes moves, it pushes a structure called the oval window in and out. This action is passed onto the cochlea, which is a fluid-filled snail-like structure that contains the receptor organ for hearing. The cochlea contains the spiral organ of Corti, which is the receptor organ for hearing. It consists of tiny hair cells that translate the fluid vibration of sounds from its surrounding ducts into electrical impulses that are carried to the brain by sensory nerves. As the stapes rocks back and forth against the oval window, it transmits pressure waves of sound through the fluid of the cochlea, sending the organ of Corti in the cochlear duct into motion. The fibers near the cochlear apex resonate to lower frequency sound while fibers near the oval window respond to higher frequency sound. Sound funnels into the ear canal and causes the eardrum to move. The eardrum vibrates with sound. Sound vibrations move through the ossicles to the cochlea. Sound vibrations cause the fluid in the cochlea to move. Fluid movement causes the hair cells to bend. Hair cells create neural signals which are picked up by the auditory nerve. Hair cells at one end of the cochlea send low pitch sound information and hair cells at the other end send high pitch sound information. The auditory nerve sends signals to the brain where they are interpreted as sounds. The outer ear collects sound waves moving through the air and directs them to the eardrum. The eardrum vibrates with sound. Sound vibrations move from the eardrum through the ossicles (bones in the middle ear) to the cochlea. Hearing, or auditory perception, is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Hearing mechanism. There are three main components of the human ear: the outer ear, the middle ear, and the inner ear. The outer ear includes the pinna, the visible part of the ear, as well as the ear canal which terminates at the eardrum, also called the tympanic membrane. The pinna serves to focus sound waves through the ear canal toward the eardrum. Because of the asymmetrical character of the outer ear of most mammals, sound is filtered differently on its way into the ear depending on what vertical location it is coming from. This gives these animals the ability to localize sound vertically. The eardrum is an airtight membrane, and when sound waves arrive there, they cause it to vibrate following the waveform of the sound. The middle ear consists of a small air-filled chamber that is located medial to the eardrum. Within this chamber are the three smallest bones in the body, known collectively as the ossicles which include the malleus, incus and stapes (sometimes referred to colloquially as the hammer, anvil and stirrup respectively). They aid in the transmission of the vibrations from the eardrum to the inner ear. The purpose of the middle ear ossicles is to overcome the impedance mismatch between air and water, by providing impedance matching. Also located in the middle ear are the stapedius and tensor tympani muscles which protect the hearing mechanism through a stiffening reflex. The stapes transmits sound waves to the inner ear through the oval window, a flexible membrane separating the air-filled middle ear from the fluid-filled inner ear. The round window, another flexible membrane, allows for the smooth displacement of the inner ear fluid caused by the entering sound waves. The inner ear consists of the cochlea, which is a spiral-shaped, fluid-filled tube. It is divided lengthwise by the organ of Corti, which is the main organ of mechanical to neural transduction. Inside the organ of Corti is the basilar membrane, a structure that vibrates when waves from the middle ear propagate through the cochlear fluid – endolymph. The basilar membrane is tonotopic, so that each frequency has a characteristic place of resonance along it. Characteristic frequencies are high at the basal entrance to the cochlea, and low at the apex. Basilar membrane motion causes depolarization of the hair cells, specialized auditory receptors located within the organ of Corti. While the hair cells do not produce action potentials themselves, they release neurotransmitter at synapses with the fibers of the auditory nerve, which does produce action potentials. In this way, the patterns of oscillations on the basilar membrane are converted to spatiotemporal patterns of firings which transmit information about the sound to the brainstem.

Types of Sound waves physics
 
03:32
Types of Sound waves physics Sound is a form of energy. Sound is that form of energy which makes us here. Sound travels in the form of waves A wave is a vibratory disturbance in a medium which carries energy from one point to another without there being a direct contact between two points. Example If we throw a piece of stone industrial surface of water in a pond, then expanding circles called ripples or water waves are formed over the surface of water when a water wave passes over the surface of water in a pond, full moment of water from the centre to the sides of the pond, only the water molecules vibrate up and down about their fixed position. A waveis produced by the vibration of the particles of the median through which it passes. example When sound waves produced by a ring Bell through air then there is no actual movement of the air from the bell only sound energy Travels through the vibration of molecules similarly water waves passes. There are two types of waves Longitudinal waves Transverse waves A wave in which the particles of the medium vibrate back and forth in the same direction in which the wave is moving, call a longitudinal wave. Diagram Longitudinal waves can be produced in all the three media: solids liquids and gases. Example The waves which travel along a spring( or slinky) when it is pushed and pulled that one end, are longitudinal waves. Diagram The Waves produced in air when a guitar wire( sitar wire, tanpura tanpura wire or violin wire) is plucked are longitudinal waves. Longitudinal wave consist of compressions and rarefactions travelling through medium. Transverse waves A wave in which the particles of the medium vibrate up and down 'at right angles' to the direction in which the wave is moving, is called a transverse wave.

Exprimentail Determination of speed of sound in air
 
01:48
Useful for CBSE, ICSE, NCERT & International Students Grade : 9 Subject :Physics Lesson : Wave motion and sound Topic: Exprimental Determination of speed of sound in air Mediums that sound can travel through. We said that sound waves travel through solids, liquids, and gases. They can travel through all states of matter that a solid has its particles packed very tightly together. Liquid particles are more loosely packed, and particles in a gas are pretty far apart. The distance between the particles affects how strong the interactions are between them. This, in turn, affects how quickly they transfer the energy of the wave. The stronger the particle interactions are, the more quickly the wave is transferred. So in general, sound travels faster in solids than in liquids, and faster in liquids than in gas.
