An air column in a pipe, which is closed...

An air column in a pipe, which is closed at one end, will be in resonance with a vibaring tuning fork of frequency 264 Hz, if the length of the column in cm is (Speed of sound = 330 m/s)

A

31.25

B

`62.50`

C

93.75

D

125

Text Solution

Verified by Experts

The correct Answer is:
A, C
`l_(1) = (332 xx 100)//4 xx 264 = 31.25 cm`
`l_(2) = 3 xx 31.5 = 93.75` cm
