Compare and contrast transverse and longitudinal waves

In both transverse and longitudinal waves; energy is transferred in form of a wave.

The difference between transverse and longitudinal waves is that:

In transverse waves; the displacement of the medium is perpendicular to the propagation of the waves.

In longitudinal waves; the displacement of the medium is parallel to the propagation of the waves.
