What are the frequency and the wavelength of the sound waves produced in water at 0 degrees C?

I can't understand this question. Is the tuning fork totally immersed in the water? Then its frequency will be radically changed and the oscillation highly damped due to the water's inertia, relative incompressibility and resistance to motion. There's no way to compute its frequency without having a lot more information (at a minimum, details about the mass, size & shape of the tuning fork) and the calculation would be complex and difficult. \nOK, so let's suppose its vibration is coupled to the water without beng immersed. Then it oscillates at 400 Hz, and this is the frequency of the sound in the water. The wavelength is then a trivial calculation.\nSurely I'm missing something. I think you should provide the answer (via the "add details" option) and see what people think then.\nEDIT: Since you added the answers, there's no disagreement on the frequency. The wavelength in any medium is the speed divided by the frequency, so there's no disagreement on the wavelength in air. However, the speed of sound in water is a parameter that many physicists have attempted to formulate. The generally agreed value at 0C is about 1430 m/s. Using the web page given below and the Marszak interactive calculator available there, I get 1402.385 m/s, which yields a wavelength of 1402.385/400 = 3.505963 m. (The other calculators on that page all agreed on the speed within 0.003 m/s.) The textbook's answer of 3.83 m implies a speed of 1532 m/s, which the Marszak calculator equates to a temperature of 42C! I think the textbook's author(s) have some explaining to do.

P=P(0)*exp(-1.1e-4*H)\n\nP(0) is the pressure at sea level. Note it's temperature dependent and it assumes a stable Boltzmann type distribution.

v = wave length * f.\n\nSo, length = v / f =   1,7m

Water continues to become more dense as it cools until just above the freezing point.  I can't remember the exact temperature off-hand, but I believe it is very near 33.5 to 34 degrees Fahrenheit.  \n\nBelow that water begins to expand and once it has frozen, its volume increases approximately 10%...that's why ice floats...less dense than the water it came from!  Cool, huh?

Water has a special property, called Anamolous behaviour of water, and this property is seen only in water.\nWater's melting point is 0 degree Celsius, and you might think that the volume increases if further heated above 0 degree celsius, and you are wrong ! Only in water, the volume of water decreases until it is heated to 4 degree celsius, and then it starts increasing, unlike any other liquid (in other liquids, replace 0 degree by their melting point). Therefore, volume of water is least at 4 degree celsius and not at 0 degree celsius. This property of water is called Anamolous Property of water or Anamolous Expansion of water.\n\n--\nWWW - Weird & Wonderful Web - http://www.kudige.blogspot.com/

You mean a 'frequency of 5.10^12Hz'\n\nCan you work it out yourself?:\n\nRemember that the speed (v) of the wave is 3×10^8 m/s,\nand that the wavelength is given by v/f\n\n[Edit: Darn, Kirchwey - don't do Glow's homework for her! ;-) ]

We want the speed of sound here.\nL=V/F, where L=wavelength, F=frequency in Hz (20000) and V=velocity of sound ~1000 ft/sec)\nL = 0.05 ft = 0.6 inch implying a 0.3 inch eardrum.\nReasonable?  I've never seen an eardrum but would think it's about that size.

2) Use stop wave:\nPlace a speaker of known, variable frequency close to a micro, the micro is connected to a microamperemeter.\nPlace that in the top of a long glass tube, slowly fill the tube with water until the the microamperemeter show a maximum. Continue filling the tube with water to get the next maximum. The distance between the two consecutive maximums is half the wavelength.\nSpeed = wavelength x frequency.\nRepeat the experiment several times and get the averange. That should be close to actual value.

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.

Electromagnetic waves are light, radio, UV, infra-red, gamma, micorwaves and go at the speed of light 186,000 miles per second (although they go a bit slower in matter). The waves themselves consist of vibrating electric and magnetic fields. Probably you know a few uses for these. For example, our eyes pick up EM waves and that allows us to *see*.\n\nSound waves are pressure waves in some material. Their speed depends on the material. Sounds goes through air at about 700 miles per hour. This is considerable slower than light.\nThese are the waves that our ears hear.\n\nWater waves are what you see on the surface of water when you throw a stone into the water. These go a *lot* slower even than sound waves.

Assuming the speed of sound in air to be 334 m/sec., and using the formula,\n\nwavelength = speed/frequency,\n\nThe longest wavelength for a human with average hearing capacity (20 Hz to 20,000 Hz) = 334/20=16.7 metres.\n\nThe shortest wavelength would be 334/20000=0.167 metres=16.7 cm\n\nThus, the wavelength limits (as per the average human audibility range) are from about 17 cm to 16.7 metres.
