A cylindrical tube, open at both ends has a fundamental frequency f in air. This tube 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

fl 2

D

3 fl 4

Text Solution

Verified by Experts

The correct Answer is:
B
f = `(v)/(2l )`
`f_(0) = (v)/(4l.) = (v)/(4 xx (l)/(2)) = (v)/(2l ) = f `
So, correct choice is b.
