Velocity of sound in air is 320 m s^(–1)...

Velocity of sound in air is `320 m s^(–1)`. A pipe closed at one end has a length of 1 m. Neglecting end correction, the air column in the pipe cannot resonate with sound of frequency

A

80Hz

B

240Hz

C

320Hz

D

400Hz

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
in general we can write for a closed end pipe
`v=((2n-1))/(4 1)`
Where `n=1,2,3,..... therefore v=(c)/(4l),(3c)/(4l),(5c)/(4l),.......`
=80,240,400,……
