An air column in a pipe, which is closed at one end. will be in resonance with a vibrating tuning fork of frequency 264 Hz if the length of the column in cm is-

A

31.25

B

62.5

C

93.75

D

125

Text Solution

Verified by Experts

`f=v/(4L), (3v)/(4L),(5v)/(4L)` …. (for closed pipe at one end)
`264=330/(4xxL) rArr L=330/(4xx264)`=31.25 cm
