Waves are disturbances that travel through a medium. Waves transport energy from one location to another without transporting matter. The height of a wave is associated with the amount of energy of carried by the wave. Wave height and wave energy are directly proportional. Thus, a lower wave height is associated with less energy. Likewise, a higher wave is associated with more energy.

The height of a wave is called the amplitude of the wave. Waves can be transverse or longitudinal.  The amplitude of a transverse wave is defined as the distance from the wave’s resting position to the lowest point of a trough or the highest point of a crest.   The amplitude of a longitudinal wave is defined as the maximum increases of pressure from a point of equilibrium that is caused when the wave passes a given point.
