A closes organ pipe of length 20 cm is sounded with a tuning fork in resonance. What is the frequency of the tuning fork? (v = 332 m/s)

A

300 Hz

B

350 Hz

C

375 Hz

D

415 Hz

Text Solution

Verified by Experts

The correct Answer is:
D
In resonance , the frequency of the fork is equal to the frequency of the organ pipe `f = (v)/(4L) = (332)/(4 xx 0.2) = 415` Hz
