An air column in a pipe, which is closed at one end, will be in resonance with a vibrating tuning fork of frequency 256 Hz, if the length of the column in centimeter is (velocity of sound in air 340 m/s)

A

`21.25`

B

`125`

C

`62.50`

D

`33.2`

Text Solution

Verified by Experts

The correct Answer is:
D
`f = (v)/(4L) implies L = (v)/(4f) = (34000)/(4 xx 256) = 33.2 ` cm
