Sound Waves

Parent Category: Physics
Sound waves are a mechanical oscillation of pressure. It is a series of vibrations that can be heard.
This is an example of the Doppler effect. Sound is composed of waves. A particular vibration produces a sound wave with a particular wavelength. When the sound source moves towards a listener the waves are "bunched up". That results in a shorter observed wavelength and thus a higher frequency. When...
How about this: What's inside the box? How Sound Wave Intensitychanges in a speaker box to outside.
The property is amplitude. Sound waves are pressure waves, and the higher the amplitude, the higher the pressure created, and the louder the sound is.
Receiving sound waves is the process by which sound travels in formof waves and is received by our eardrums to be heard.
The term "duration" applies to the length of sounds. Duration andsound pressure level are the determiners of a sound's loudness.
Sound waves are vibrations through a medium, such as air or water. The energy travels from the vibrating source and vibrates molecules in the medium, which push others sending a wave through the medium. Without a medium, there's nothing to vibrate and sound cannot travel.
What we perceive as "sound" is in fact a neural reaction to changesin air compression that our brains interpret as "sound". Air iscompressed by some mechanical action (such as a speaker movinginwards and outwards), and the outer ear acts as a bit of a lens tocapture and guide these compressed air...
Do to there massive size ears
okay whoever said that mass affected pitch is just stupid.... Frequency and amplitude affect pitch
4mm / (1.54mm/us) = 1 sound wave every 2.5974us. 1,000,000us per second. 1,000,000/2.5974 = [385,000Hz] With proper sigfigs = 4 x 10^5 (if the values given here are exact)
vibrating materials
curtains, wardrobes, cushions, clothes
The thicker and denser the medium, the slower sound will travel through it. The density of the medium matters because the denser the substance is, the more material the sound has to vibrate per inch it travels through the substance. This forces it to slow down.
All "waves" are energy. In this case, music is a tremendouslycomplex series of waves caused by air compression of differingfrequencies, phase, and amplitude. But they are still waves, causedby movement of the air - basic physics tells you that moving airhas force (however small) and therefore energy...
Neither - they are both the same amplitude, which is typicallyinterpreted as "power". A larger amplitude will have greater"power" in that it will sound "louder".
Sound waves are known as longitudinal waves.
Unlike electromagnetic waves such as radio and television or lightwhich can travel through the vacuum of space, sound waves travel bythe compression and decompression of molecules in the mediumthrough which they are passing. The medium must be compressible,whether it be gas, liquid or solid, and...
Sound waves are the means by which echolocation works. First,sounds are transmitted by an organism or a device. Sound waves will"bounce" off of objects and reflect back towards the source (infact, in many different directions). Echolocation works bylistening for these echoes and their differing...
Sound waves are just vibrating air that have frequencies.
air density (and thus air pressure, temperature, wind andrelative humidity); and . motion of the source (causes Doppler effect).
Sound energy is a form of mechanical energy, and is produced whenan object vibrates. The sound vibrations cause waves of pressurethat travel through air, water, wood, or metal.
if they are in a void no matter how much the object vibrates itwon't produce any sound waves
The energy in a sound wave is related how the air pressure changesas the wave move through the air. A moving object such as avibrating drum head causes pressure disturbances in the air, whichtravel away from the object. The higher the pressure difference(between maximum and the 'normal' air pressure...
A sonographer uses ultrasound to imagebody organs.
Amplitude. As the amplitude of the sound wave increases, the soundbecomes louder.
Ultrasound can be used to image abdominal organs. There is anarticle on the website radiologyinfo dot org. But I cannot figurehow to post the link, here.
Frequency (measured in Hertz, which is cycles per second). Higherfrequency, or more cycles (or oscillations) per second, will soundas a higher pitch.
because sound travels pretty slow. thats why if your in the veryback at a rock concert, and you see the drummer hit a drum, and youhear the drum a half a second or so later. in marching band, youwant the sound to line up for the audience. to achieve this, listenback, and center. usually the drumline...
Difference is in their frequency, audible sound waves is between 12 Hz and 20,000 Hz, Ultrasound waves is any sound that has a frequency beyond the 20,000 Hz limit
Pitch is affected by the frequency and wavelength of a sound wave. When the frequency is lower there are not as many waves per second, and the wavelength becomes longer. A low pitch is made by the low frequency and long wavelength of a sound wave.
.. because the earth sampak to the moon :)) .. HAHAHAHA
Sound is a compression or rarefication of air. That compression is measured in frequency (Hertz) or cycles per sec . 440 Hertz is A or "Concert Pitch"
Ultrasound is a sound generated at a frequency above the human hearing range, i.e. above 20,000Hz. Ultrasound is useful as it's high frequency means it is a high energy sound wave, allowing it to penetrate easily through thicker, more dense mediums. The most common use of ultrasound is sonography,...
Sound waves are everywhere. You could find them in such places like the television, or the radio, or even instruments. The vibration of a string on a guitar or a reed on a clarinet, produces sound waves.
Grounding would be more appropriate
Loudness is the quality of a sound that is the primary psychological correlate of physical strength (amplitude). It is a feeling, which is neither the sound pressure as field quantity nor the acoustic intensity as energy quantity. Scroll down to related links and look at "Loudness - Wikipedia".
Short and simple: Sound is a compression (or pressure) wave. There are two things that affect the speed of sound, the density of a material and its compressibility. Specifically, the speed of sound is proportional to the square root of the ratio. v=sqrt(B/rho) v=speed of sound. B= bulk...
it travels through rock quickest even if they are both solids eking
A bounced sound wave is acalled an echo. You can hear these echos when you yell into a cave or a crevasse or an abyss.
Speed = distance / time [m /s] likewise: Speed of wave = wavelength x frequency [m /s] Since sound waves travel at a fixed speed through a medium* a drop in frequency must cause a corresponding increase in wavelength *Not always true. In water of example, lower frequency waves travel faster...
Sound waves are described as pressure waves because the sound wehear is caused by the variations in air pressure. Compression andratification of air make the eardrum move.
Why is produced rarefaction and condensation during the sound travelling in the medium?
Because of the density of water, it does not heat up as quickly when exposed to light, and is, therefor, colder than the air around it. This means that the water is constantly pulling heat energy from the air around it, making the air directly above a body of water colder than that above land, and...
An antenna is specifically designed to "pick up" electromagnetic waves. These are typically amplified and converted to electronic signals in some sort of circuit. That circuit can then provide a signal to another device to produce output. This happens with a radio when the antenna gets radio waves...
Sound needs gases to travel through, therefore it does not exist in a vacuum. In other words to my knowledge there is no experiments where sound is created in a vacuum.
Waves transmit energy.
No, there is no sound in space because there is no air. Without air sound will not travel anywhere. Sound is created by a wave moving. For a wave to move, it needs a medium. Sound travels in air or water. There is no air or water in the vacuum of space. Believe it or not...this is actually false...
To create a shock-wave you need to have some form of medium to support it. As space is well neigh a perfect vacuum, No.
The Infra sound (way below our hearing capacities) The normal sound (within our hearing capacity) The Ultra Sound (way above our hearing capacities)
Has to be completely closed area no air could be flowing in or out so cover up all the air holes as good as you can and your good
A sound wave in the air is called a Longitudinal wave.
Produced by reflected sound waves over 17m away?
The amplitude is the maximum amount it sways from the neutralposition. If it oscillates about zero, then it would vary from avalue of +A to -A, where A is the maximum Amplitude. The units of Awill be determined by the type of wave.
the higher the pitch will be.
Because the sound waves have no where to go and bounce off your hand right back to your ear.
Sound travels faster through dense material. This is because molecules in a dense(solid) medium are much closer together than those in a liquid or gas(thin), allowing sound waves to travel more quickly through it.
The sound must travel across the lake and back.
the distance between the girl and the wall is 1650m. i calculated it using the formula ((v*t)/2).
Scientists do not need perfect pitch to analyse sounds because they use instruments to detect and assess the noise.
humans can't hear the sound waves of lesser than 20Hz and greater than 20,000Hz.Humans only can hear the sound with in the range of 20-20,000Hz
Beats are the direct result of the interference that is caused by the difference in frequencies of two sound waves.
by using gadgets or other thing in music..
Radiowaves meduim- elecromagnetic feilds soundwaves medium- matter speed of sound in air- 330m/s speed of light in vaccum- 3*10^8 m/s radiowaves- transverse soundwaves- longitudanal
sound sent through liquids or gases is called compression waves sound sent through solids is called longitudinal and transverse waves
Yes. Sound depends on the medium it is in. Sound vibrates that medium to produce waves at different frequencies. Sound travels better the more dense the medium. Sound travels faster in water than air and better in steel than in water.
Longitudnial waves (or pressure waves).
The rebound of a wave is called a reflection, but we often use the term echo to refer to the rebounding sound wave.
Of the four materials, wire will carry the sound best because it is the most dense.
From what part of the body,And then again there is tone attitudeand emotion too
they are different by the way they behave and the way it is different is one behaves like they should and the other one behaves bad.
Pitch is the word used to describe the frequency of the sound waves. A higher pitch means a sound of higher frequency and a lower pitch means a frequency of lower pitch. Higher pitched sounds are shriller than lower pitched ones.
The fingerprint of sound can come in pulsation and percussion
You would be able to hear yourself scream. ________________ Of course. Anyone listening in on your space suit's communication device would hear you. And they probably wouldn't care much for it, especially if they are in suits themselves.
It is when a group of people die in a circuit thanx for reading!!!!!!!!!!!!
Sound waves travel faster through liquids than through gases because of the higher density of molecules in liquid.
Particles, e.g gas particles in air, because sound travels through the vibration of particles. Sound waves cannot travel in a vacuum, as there are no particles.
Space or a vacuum as there are no atoms...
Sound wave is is generated by a vibrating object.Whereas, seismic wave is the vibration generated by an earthquake or explosion.
The energy in a sound wave is both kinetic and potential. Just as in a vibrating spring, the medium has mass and moves and so moving mass is kinetic energy. Just as in the spring there is compression and rarefaction, so there is elastic potential energy. In fact, these two are equal,...
The sound wave is actually a pressure wave. The air molecules movetogether and then farther apart, creating volumes which alternatebetween (slightly greater than normal pressure) and (slightly lessthan the normal pressure). A volume, at a specific pressure, can beexpressed as energy (pressure times...
