Physics - Sound Wave Question with Solution | TestHub

The speed of sound in a medium depends on both its elastic property (restoring force) and its inertia property (mass density). Elasticity determines how quickly particles return to their original positions, while inertia determines their resistance to motion.

The speed of sound $v$ is given by:

$$v=\sqrt{\frac{B}{\rho }}$$

where $B$ is the bulk modulus (elastic property) and $\rho$ is the density (inertia property).
