What term describes the bottom of a wavelength?

Explanation:
In wave terms, the lowest point of a cycle is called the trough. A wave has a top point, the crest (or peak), and a bottom point, the trough. Amplitude describes how far the wave moves from its rest position, typically the distance to the crest or to the trough, but it isn’t the name of the bottom location itself. So the bottom of a wavelength is the trough.
