What type of wave travels faster through solids than it does through gases?

Longitudinal waves travels faster through solids than it does through gases

Explanation:

As we know that longitudinal waves travels through all types of mediums and the speed of longitudinal waves is given as

here we know that

E = elasticity of the medium

= density of the medium

now here we know that elasticity of solids is much more than the elasticity of gases

So the speed of longitudinal waves in solids is more than the speed of waves in gases
