Longitudinal and Transverse energy waves are the two types.
Transverse wave - A transverse wave is a wave in which the motion of the medium is perpendicular to the motion of the wave.
Longitudinal wave - A longitudinal wave is a wave in which the motion of the medium is parallel to the motion of the wave.
Water waves are mostly transverse. The water moves up and down while the wave travels over the surface of the water.
Sound waves are longitudinal. The air vibrates back and forth along the same direction as the wave is traveling.
