A tuning fork of frequency `500 H_(Z)` is sounded on a resonance tube . The first and second resonances are obtined at `17 cm` and `52 cm` . The velocity of sound is

A

350 m/s

B

520 m/s

C

700 m/s

D

170 m/s

Text Solution

Verified by Experts

The correct Answer is:
A
`v=2n(l_2-l_1)`
`=2xx500xx[52-17]xx10^(-2) = 10 xx 35`
=350m/s

A tuning fork of frequency 440 Hz resonates with a tube closed at one end of length 1.8 cm and diameter 5 cm in fundamental mode. The velocity of sound in air is

Assertion: The length of the glass tube in air column resonating experiment is 75 cm. If velocity of sound in air is 330ms^(-1) , The experiment connot be performed with a tuning fork o frequency n=482 Hz. Reason: If l_(2)andl_(1) are first and second resonating lengths in air column resonating experiment, then velocity of sound V=2n(l_(2)-l_(1))
