A Crest point on a wave is the highest point of the wave. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point of the wave.
The crest of a wave is the point on the medium that exhibits the maximum amount of positive or upward displacement from the rest position. Points C and J on the diagram represent the troughs of this wave.
trough - the lowest point below the rest position. amplitude - the maximum displacement of a point of a wave from its rest position. wavelength - distance covered by a full cycle of the wave ...
A wave’s crest is its highest point, and its trough is its lowest point. A wave’s amplitude is the maximum distance (positive or negative) a wave reaches from its rest position. Wavelength is the distance between the same spot on two sections of a wave.
Crest: the highest point of the wave. Trough: the lowest point of the wave. Wave height: the distance between the crest and the trough. Wavelength: the distance between two identical points on successive waves, for example crest to crest, or trough to trough. Wave steepness: the ratio of wave height to length (H/L).
A wave is described by its wavelength (or the distance between two sequential crests or two sequential troughs), the wave period (or the time it takes a wave to travel the wavelength), and the wave frequency (the number of wave crests that pass by a fixed location in a given amount of time).

Its wavelength is the distance from crest to crest or from trough to trough. The wavelength can also be thought of as the distance a wave has traveled after one complete cycle—or one period. The time for one complete up-and-down motion is the simple water wave’s period T .
