Medium
Why is the speed of sound higher in solids and liquids as compared to gases?
(N/A) The speed of sound in a medium is given by the formula $v = \sqrt{\frac{B}{\rho}}$,where $B$ is the bulk modulus and $\rho$ is the density of the medium.
Although the densities $(\rho)$ of solids and liquids are much higher than those of gases,the speed of sound is higher in them because they are much less compressible than gases.
This means that solids and liquids have a significantly greater bulk modulus $(B)$ compared to gases,and the increase in the bulk modulus far outweighs the increase in density,resulting in a higher speed of sound.
