Crests and troughs. Waves have moving crests (or peaks) and troughs. A crest is the highest point the medium rises to and a trough is the lowest point the medium sinks to. Crests and troughs on a transverse wave are shown in Figure 1. A crest is a point on the wave where the displacement of the medium is at a maximum.
According to the eyewitnesses, the wave crest was only between 25 and 50-foot wide, and the front slope was steeper than the back of the wave. The event that produced the largest wave ever recorded was later studied and modeled by Hermann M. Fritz (1999), Charles L. Mader and Michael L. Gittings (2002). Learn how waves are formed.
