An open pipe is suddenly closed at one end with the result that the frequency of third harmonic of the closed pipe is found to be higher by `100 Hz` then the fundamental frequency of the open pipe is

A

`100 Hz`

B

`300 Hz`

C

`150 hz`

D

`200 Hz`

Text Solution

Verified by Experts

The correct Answer is:
D
`5xx(v)/(4l)-(v)/(l)=100` or `(v)/(l)((5)/(4)-1)=100`
or `(v)/(4l)=100` or `(v)/(2l)=200` or `v=200Hz`
