Change in temperature of the medium changes.

A

frequency of sound waves.

B

amplitude of sound waves.

C

wavelength of sound waves.

D

loundness of sound waves.

Text Solution

Verified by Experts

The correct Answer is:
C
At absolute temperature T of air, velocity of sound in air is `v prop sqrtT" "…(1)`
Also we have `v = f lamda implies lamda prop v " "…(2) (because f =` constant)
From relations (1) and (2), we have `lamda prop sqrtT`
`implies Wavelength of wave will change with the change in temperature.
