The frequency does not change (actually it does due to added mass of water but not to first order)
The velocity of sound in water is greater than in air so the wavelength will be greater.
Tair = period in air = 1/400
wavelength in air = Vair * 1/400
Twater = 1/400
wavelength in water = Vwater * 1/400
A vibrating 400.0Hz tuning fork is placed in fresh water. What is the frequencyin herbs and the wavelength in meters
(A) within the water at 25c
(B) when the sound waves move into the air at 25c
