In a Kundt's tube , the length of the iron rod is `1 m`. The stationary waves frequency `2500 Hz` are produced in it. The velocity of sound in iron is

A

`1250 m//s`

B

`2500 m//s`

C

`5000 m//s`

D

`10,000 m//s`

Text Solution

Verified by Experts

The correct Answer is:
C
`(lambda)/(2) = 1 m or lambda = 2 m`
`v = f lambda = 2500 xx 2 m//s = 5000 m//s`
