Charge in temeprature of the medium changes

A

frequency of sound waves

B

amplitude of sound waves

C

wavelength of sound waves

D

loudness of sound waves

Text Solution

Verified by Experts

The correct Answer is:
C
Speed of sound wave in a medium `vpropsqrt(T)` (where T is temperature of the medium) Clearly, when temerature changes speed also changes.
AS,` " " v=vlambda`
where v is frequency and `lambda` is wavelength .
Frequency (v) remains fixed
`implies" " V=proplambda " or " lambdapropV`
As does not change, so wavelength `(lambda)` changes.
