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

2f

B

f

C

f/2

D

3f/4

Text Solution

Verified by Experts

The correct Answer is:
B

`n_(0)=(v)/(2l)n_(c)=(v)/(4(l//2))=(v)/(2l)`
