A tuning fork having frequency `256 Hz` emits a wave which has a wavelength of `1.35 m`. Find the speed of sound in air.

A

`256 m//s`

B

`345.6 m//s`

C

`245.6 m//s`

D

`355.6 m//s`

Text Solution

Verified by Experts

The correct Answer is:
B
Here, frequency of the tuning fork,`v = 256 Hz`
wavelength of the wave emitted, `lamda = 1.35 m`
Speed of sound in air, `v = v lamda = 256 xx 1.36 = 345.6 m//s`.
