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 its length is in water. The fundamental frequency of the air column is now
(a) `f // 2`
(b) `3 f // 4`
(C ) `f`
(d) `2f`

A

`(f)/(2)`

B

`(3f)/(4)`

C

`f`

D

`2f`

Text Solution

Verified by Experts

The correct Answer is:
C
`v=f_(1)lamda_(1)=f_(2)lamda_(2)rArr f_(2)lamda_(2)rArr fxx2L=f'xx2LrArrf'=f`
