Answer:
Longitudinal waves travels faster through solids than it does through gases
Step-by-step 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
