What term describes the lowest point of a transverse wave?

Explanation:
In a transverse wave, the medium moves up and down as the wave travels forward. The highest point reached is the crest, and the lowest point reached is the trough. This trough corresponds to the maximum downward displacement from the rest position, opposite the crest’s maximum upward displacement. The amplitude measures how far the medium moves from equilibrium, not a specific point on the wave, and the wavelength is the distance between repeating points like crest to crest. So the term for the lowest point is trough.
