A pipe open at both ends has a fundamental frequency f in air. The pipe is dipped vertically in water so that half of it is in water. The fundamental frequency of the air column is now :

A

2f

B

f

C

`f/2`

D

`(3f)/4`

Text Solution

Verified by Experts

The correct Answer is:
B

The fundamental frequency in case (a) in `f=v/2l`
The fundamental frequency in case (b) is
`f.=v/(4(l//2))=u/(2l)=f`
