An air column in a pipe, closed at one end, will be in resonance with a vibrating tuning fork of frequency `680 Hz` if the length of the column in metres be `v = 340 m//s`
(Choose the incorrect option)

A

`0.25`

B

`0.125`

C

`0.375`

D

`0.685`

Text Solution

Verified by Experts

The correct Answer is:
A
`lambda = (v)/(f) = (340)/(680) = 0.5 m`
`L = (lambda)/(4), (3 lambda)/(4), (3 lambda)/(4)…`
`= 0.125 m, 0.375 m, 0.625 m, …`
