In a resonance tube, using a tuning fork of frequency `325 Hz`, the first two resonance lengths are observed at `25.4 cm` and `77.4 cm`. The speed of sound in air is

A

338 `ms^(-1)`

B

328 `ms^(-1)`

C

330 `ms^(-1)`

D

320 `ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
a
Velocity of sound in air,
`v=2n(l_(2)-l_(1))=2xx 325(77.4-25.4)`
`rArr v(650xx52)/100=338ms^(-1)`
