how would you measure the velocity of sound?

There are any number of ways to do this. The earliest experiments conducted by the Babylonians simply consisted of using 3 people.\n\nTwo people stand a set distance apart, say half a mile.  Beside one of them stands the third person. Person A makes a noise (firing a gun would be good). Person C stands beside person A and either starts countung (as was originally done) or activates a stopwatch when the noise is made. When person B, who is half a mile away, hears the noise he imediately responds by making the same noise. When person C hears that noise he stops counting. \n\nThe speed of sound will be approximately the time person C was measured, in miles/second. \n\nYou can get more accurate by working out how long it takes for a  person to react to a sound and make their response sound and subtracting that from the figure. You can also increase accuracy by using a range of distances, up to several miles, and by ensuring their is no wind. But the basic experiment will give you the approximate measurement speed of sound.

Sure.  An oscilloscope ought to do the trick.

This is ultrasonic, not electromagnetic, so C is irrelevant.  The equation is:\nF=V/L where V=sound velocity in water (~1475 m/s), F=frequency in Hz, L=wavelength (0.0003 m)\nResult is you need 4.9 MHz or higher.

The speed of sound isn't even close to the speed of light. The speed of sound in air is usually given as 343 meters per second at sea level in air and the speed of light is approximately 3 X 10^8 meters per second (300,000,000 m/s)in a vaccuum.

The 'speed of sound (from Latin celeritas, "velocity") varies depending on the medium through which the sound waves pass. It is usually quoted in describing properties of substances (e.g. see the article on sodium). In conventional use and in scientific literature sound velocity v is the same as sound speed c. Sound velocity c or velocity of sound should not be confused with sound particle velocity v, which is the velocity of the individual particles. More commonly the term refers to the speed of sound in air. The speed varies depending on atmospheric conditions; the most important factor is the temperature. The humidity has very little effect on the speed of sound, while the air pressure has an effect (see equations later in the page). Sound travels slower with an increased altitude (elevation if you are on solid earth), primarily as a result of temperature and humidity changes.

If you can measure the *frequency*, you know the wavelength.\n(As the wavelength is just the frequency divided by the speed of sound.)  I found a calculator that does this for you:\nhttp://www.sengpielaudio.com/calculator-wavelength.htm\n\nIdeally you would get an oscilloscope to measure the frequency.\n\nIf you don't have access to one, if you have a guitar tuner, you could measure the frequency (the tuner will tell you the pitch, say A#, and you can look up the frequency of that pitch in a music book).\n\nOr if you have a bunch of tuning forks or a pitch pipe, you could get an approximation.\n\nIf you have an ocilloscope, don't forget to get the precise speed of sound at your elevation (sound travels a bit faster at sea level, than if you live in, say, Denver).  (Note that the calculator link above gives you a place to enter the speed of sound where you live.)  If you're using a guitar tuner or tuning forks, they are only approximations anyway, so the exact speed of sound for your elevation won't make a difference.  \n\nP.S.  I found a reference to a sound analyzer you can get for your computer!  The software is free, but it needs a soundcard in your computer (which you probably have).  It uses the information from a microphone in your computer to give you the frequency and wavelength of the musical note.  It's kinda cheating if this is for a science-fair project ... but maybe this is what you want.\nhttp://www.relisoft.com/Freeware/freq.html

The speed of sound varies depending on the material it is travelling through, the pressure, altitude and temperature.\n\nOn the assumption you're talking about air and that you're at sea level under normal atmospheric conditions then 340m/s would be the speed at 14 degrees C and 330m/s would be the speed at minus 1 degree C - so they're both right.

The sound is measured in decibels. There should be a tag inside the smoke detector with that information.

341m/s but it changes according to the weather conditions in humid climate it is faster as compared to dry.and yeah sound does not travel through vacuum\nspeed of sound in solids > liquids > gases

You tell me, you the one doing the lab probably.\n\nOne of several possible objects could be to identify the speed of sound.  You might also be studying the nature of waves (wavelength, frequency, ...).

simply use a hydrometer.

This requires the use of doppler shift formula for a moving source and stationary observer:\n\nf = f0 ( v / ( v + u ) )\n\nf0 = actual frequency = 5\nv = speed of wave = 20\nu = relative velocity of source away from observer = -10\n(since travelling toward)\n\nf = observed frequency = 10 Hz\n\nNow velocity = v = fl = frequency * wavelength\n\nso wavlength l = v / f = 20 / 10 = 2m

The velocity of sound in air or the frequency of a tuning fork is determined using the principle of resonance of air column.\n\nIn that experiment the length of air column is adjusted and the tuning fork is used to vibrate the air column; the water or glass is not vibrating so much and can be considered as having no vibration at all. \n\nWhen the frequency of tuning fork is high the resonating length of air column is less.\n\nHere in your case, the water and hence the glass are vibrating, and sound is passed through the air. No stationary sound wave is formed above the water level.\n\nThis is a case of forced vibration and the vibration frequency depends only upon the vibration of water particles, the glass vibrates with the frequency of the water particles; the glass is not left free to vibrate with its natural frequency.\n\nIf you have water to some level in the glass and strike the glass with some hammer and leave it to vibrate then only the glass will vibrate with its natural frequency.
