An open pipe of length 2m is dipped in ...

An open pipe of length ` 2m` is dipped in water . To what depth ` x` is to be immersed in water so that it may resonate with a tuning fork of frequency `170 Hz` when vibrating in its overtone . Speed of sound in air is `340 m//s`

A

0.5m

B

0.75m

C

1m

D

1.5m

Text Solution

Verified by Experts

The correct Answer is:
A
`2n=(v)/(2l_0)`
`2xx170=(340)/(2l_0)`
`2l_0 = 1`
l_0 = 1/2 = 0.5m`
