What is a crest of a wave?
What are the troughs of a wave?
What is the distance between two successive crests?
How does a wave move in a trough?
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.
Points A, E and H on the diagram represent the crests of this 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.

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. of one wave to the crest of the next wave. But it doesn't matter where you measure it - as long as it is the same point on each wave. The symbol for wavelength is the...
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).
Apr 14, 2023 · The highest part of the wave is called the crest. The lowest part is called the trough. Wave height is the overall vertical change in height between crest and trough. The distance between two successive crests (or troughs) is the length of the wave, or wavelength.
