If an open pipe is suddenly closed with ...

If an open pipe is suddenly closed with the result that the second overtone of the closed pipe is found to be higher in frequency by 100 Hz than the first overtone of the original pipe, then the fundamental frequency of open pipe will be

A

100Hz

B

300Hz

C

150Hz

D

200Hz

Text Solution

Verified by Experts

The correct Answer is:
D
`2n_c - 3n_0 = 150`
`therefore n_c = (n_0)/(2)`
`2.5 n_0-2n_0 = 100`
`0.5n_0 = 100`
`n_0 = 200`
