Question
Explain why solids can support both longitudinal and transverse waves, but only longitudinal waves can propagate in gases, and
✓

Answer

This is because solids have both volume elasticity and shape elasticity. Therefore both transverse and longitudinal waves can pass through them. On the other hand gases have only volume elasticity of shape and no shear elasticity hence only longitudinal waves can propagate in gases.
