A tuning fork of frequency `480 Hz` is used in an experiment for measuring speed of sound (v) in air by resonance tube method. Resonance is observed to occur at two successive lengths of the air column, `l_(1) = 30 cm` and `l_(2) = 70 cm`. Then, `v` is equal to :

A

`379ms^(-1)`

B

`332 ms^(-1)`

C

`338 ms^(-1)`

D

`384 ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
`lamda=2(l_(2)-l_(1))` (Resonance column exp.)
`=2xx40cm V=480xx80=384m//s`
