Waves of frequency 1000 Hz are produced ...

Waves of frequency `1000 Hz` are produced in a Kundt's tube . The total distance between `6` successive nodes is `82.5 cm`. The speed of sound in the gas filled in the tube is

A

`33 cm//s`

B

`33 m//s`

C

`330 m//s`

D

`660 m//s`

Text Solution

Verified by Experts

The correct Answer is:
C
`( 5lambda)/(2) = 82.5 or lambda = (2 xx 82.5)/( 5) cm or lambda = 33 cm`
`c = 1000 xx (33)/( 100) m//s = 330 m//s`
