A tuning fork vibrating at 512Hz is struck in air.
a. (a) If the speed of sound in air is 340m/s, calculate the wavelength of the sound produced.
b. (b) The same tuning fork is then held over the mouth of a deep water tank. Taking the speed of sound in water as 1500m/s, calculate the wavelength of the sound in water.
c. (c) By what factor does the wavelength change when the sound travels from air to water?
