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

f/2

B

4

C

3f/4

D

2f

Text Solution

Verified by Experts

The correct Answer is:
A
When the tube is dipped in water , it become a closed pipe of length L/2 . Its fundamental frequency is `f. = (v)/(4(L//2)) = f`
