For fundamental frequency f of a closed ...

For fundamental frequency `f` of a closed pipe, choose the correct options.

A

If radius of pipe is increased, `f` will decrease

B

If temperature is increased, `f` will increase

C

If modecular mass of the gas filled in the pipe is increased, `f` will decrease.

D

If pressure of gas (filled in the pipe) is increased without change in tempreature, `f `will remain unchanged

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
`f = (nu)/(4(l + 0.6 r)) = sqrt(gammaRT//M )/(4 (l + 0.6 r))` (d) `nu` does not depend on pressure if temperature is kept constant.
