A tuning fork makes `256` vibrations per second in air. When the speed of sound is `330 m//s`, the wavelength of the note emitted is :

A

`1.29` m

B

`2.1` m

C

`0.5` m

D

`0.9` m

Text Solution

Verified by Experts

The correct Answer is:
a
Wave motion is a disturbance travelling through a
medium. Wave velocity `v = nlambda`
This relation holds for transverse as well as longitudinal
waves.
Here, `v(s) = 330ms^(-1), n = 256 `
So `lambda = v_(s)/n=330/256=1.29 m`
