Longitudinal waves require a medium to propogate . Example are sound waves
Sound wave
The velocity of sound is the highest when travelling through a solid. Sound travels fastes in a solid, then in a liquid, and slowest through a gas.
Sound.
because its a mechanical wave, it requires an action to be formed and that produces energy ( as a sound)
Sound is a longitudinal wave and a light wave is a transverse wave. Sound requires a medium to travel through but light can propagate without any medium.

A mechanical wave such as a sound wave requires a medium to travel through.
Because sound doesn't traverse through a vacuum, sound requires air to pass through in a wave (sound wave).
a mechanical wave that requires a medium through which to travel.
it is sound that requires a medium to travel .. light is an electromagnetic wave ..it doesn't require a medium..
Sound is not an electromagnetic wave, which can pass through a vacuum, but a vibration wave which requires matter to vibrate. A vacuum has no matter to vibrate, therefor sound cannot pass through it.
