A cylindrical tube, open at both ends, has a fundamental frequency v. The tue is dipped vertically in water so that half of its length is inside the water. The new fundamental frequency is

A

`f//2`

B

`3f//4`

C

f

D

`2f `

Text Solution

Verified by Experts

The correct Answer is:
C
For open pipe ` =n_(0) = v//2l`, for closed pipe `n_(c ) = v//4l. = v//4 (l//2) = v//2l, n_(c ) = n`
