$v_1$ and $v_2$ are the velocities of sound at the same temperature in two monoatomic gases of densities $\rho_1$ and $\rho_2$ respectively. If $\frac{\rho_1}{\rho_2} = \frac{1}{4}$,then the ratio of velocities $v_1$ and $v_2$ will be

The frequency of a rod is $200 Hz$. If the velocity of sound in air is $340 m/s$,the wavelength of the sound produced is:

Speed of sound in air near room temperature is approximately

$A$ sound wave passing through an ideal gas at $NTP$ produces a pressure change of $0.001 \ dyne/cm^2$ during adiabatic compression. The corresponding change in temperature $(\gamma = 1.5$ for the gas and atmospheric pressure is $1.013 \times 10^6 \ dyne/cm^2)$ is:

The speed of sound in oxygen $(O_2)$ at a certain temperature is $460 \, m/s$. The speed of sound in helium $(He)$ at the same temperature will be ............. $m/s$ (assume both gases to be ideal).

$A$ source of frequency $f$ is emitting sound waves. If the temperature of the medium increases,then
