If v is the speed of sound in air then the shortest length of the closed pipe which resonates to a frequency n

A

`(v)/(2n)`

B

`(v)/(4n)`

C

`(4n)/(v)`

D

`(2n)/(v)`

Text Solution

Verified by Experts

The correct Answer is:
B
In closed pipe lowest frequency (shortest length of pipe) is given by `v=nlamda=nxx4lamda`
`impliesl=(v)/(4n)`.
