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

A

`v//2`

B

`v`

C

`3 v//4`

D

` 2 v`

Text Solution

Verified by Experts

The correct Answer is:
B
`f_(open) = (v)/( 2l) = v`
`f_(closed) = (v)/(4 ((l)/(2))) = (v)/( 2l) = v`

In given figure, A uniform cylindrical tube closed at one end, contains a pallet of mercury 5cm long. When the tube is kept verticaly with the closed end downward, the length of the air column trapped is 30cm . Now the tube is inverted so that the closed end goes up find the new length of the air column trapped. atmospheric pressure =75cm of mercury. (Assume temperature remains constant in this process)
