Speed of sound is air is 340 m/s. The length of air column is 34 cm. The frequency of `5^(th)` overtone of pipe closed at one end is

A

2000Hz

B

2750Hz

C

2500Hz

D

2800Hz

Text Solution

Verified by Experts

The correct Answer is:
B
`n_c = (v)/(4l_c) = (340)/(4xx34xx10^(-2))`
`=1000/4 = 250`
`n_5 = (2p+1)n_c`
`=11n_c`
`=11xx250=2750Hz`
