If a resonance tube is sounded with a tuning fork of frequency 256 Hz, resonance occurs at 35 cm and 105 cm. The velocity of sound is about

A

358 m/ s

B

512 m/s

C

524 m/s

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
`v = 2 f (L_(2) - L_(1)) = 2 xx 256 xx (105 - 35) xx 10^(-2) = 358.4` m/s
