An open pipe resonates with a tuning for...

An open pipe resonates with a tuning fork of frequency `500 Hz` . It is observed that two successive notes are formed at distance `16 and 46 cm` from the open end. The speed of sound in air in the pipe is

A

`230 m//s`

B

`300 m//s`

C

`320 m//s`

D

`360 m//s`

Text Solution

Verified by Experts

The correct Answer is:
B
` (lambda)/(2) = 46 - 16 rArr (lambda)/(2) = 30 cm`
or `lambda = 60 cm`
`:. v = lambda f = (60)/(100) xx 500 = 300 m//s`
