Vedclass · Answer

(A) The velocity of a sound wave in a medium is given by the formula $v = \sqrt{\frac{K}{\rho}}$,where $K$ is the bulk modulus and $\rho$ is the density of the medium.The classification of sound waves into ultrasonic,infrasonic,and audible ranges is based solely on their frequency (or wavelength). The speed of a sound wave depends only on the physical properties of the medium (such as elasticity and density) and is independent of the frequency of the wave.Therefore,in a given medium,the speeds of ultrasonic,infrasonic,and audible waves are nearly equal,i.e.,$V_u \approx V_i \approx V_a$.

Ultrasonic,infrasonic,and audible waves travel through a medium with speeds $V_u$,$V_i$,and $V_a$ respectively. Then:
