    The bottom of a wave is called the trough, the top i the crest. The amplitude or height of the wave is measured from the midpoint up or down.

    Source(s): I have been sailing in 10 foot waves tht sure seemed like they should be called 20 footers .

    I don't think that the bottom, as you are probably thinking, has a name. As a diver I experience it a surge. That is a back and forth motion of the water when a wave passes over. A wave does not touch the bottom until the water depth is the same as the height of the wave that you see on the surface, then it will rise as the bottom rises before cresting.

    The lowest part is the "trough", and the highest part is the "crest".
