The speed of sound in air and water is 340 m/s. and 1420 m/s respectively. If sound waves have a wavelength of 2m in air, then the frequency of the same sound waves in water will be

A

100 Hz

B

125 Hz

C

340 Hz

D

170 Hz

Text Solution

Verified by Experts

The correct Answer is:
D
`n_("air") = (Va)/(lamda a) = (340)/(2) = 170 Hz`
There is no change in frequency when they travel in water.
