A pipe opened at both ends prpduces a note of
frequency `f_(1)`. When the pipe is kept with `3/4th` of its
length in water, it produces a note of frequency `f_(2)`.
The ratio `f_(1)/f_(2)` is

A

`3/4`

B

`4/3`

C

`1/2`

D

2

Text Solution

Verified by Experts

The correct Answer is:
c
For open pipe, `f_(1)=v/(2l)`
and for closed pipe `f_(2)=v/(4xx(l/4))=v/l=2f_(1) rArr (f_(1))/(f_(2))=1/2`
