Vedclass · Answer

(B) The speed of sound $v$ in a gas is given by the formula $v = \sqrt{\frac{B}{\rho}}$,where $B$ is the bulk modulus of elasticity and $\rho$ is the density of the gas.Since the speed of sound $v = f \lambda$,where $f$ is the frequency and $\lambda$ is the wavelength,we have $\lambda = \frac{v}{f} = \frac{1}{f} \sqrt{\frac{B}{\rho}}$.Thus,the wavelength $\lambda$ depends on the frequency of the sound source and the physical properties of the medium (density and elasticity).Among the given options,the density and elasticity of the gas are the fundamental properties of the medium that determine the speed of sound,which directly influences the wavelength.
