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

Options

A. If radius of pipe is increased f will decrease
B. If temperature is increased f will increase
C. molecular 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 temperature, f will remain unchanged

Answer

A, B, C, D

Explanation

Fundamental frequency `f=(V)/(4L+0.6r)=(sqrt((gammaRT)/(M)))/(4L+0.6r)=(sqrt((gammaP)/(rho)))/(4(L+0.6r))`
