Which term describes the lowest point of a wave?

Explanation:
In waves, the lowest point is the trough. Imagine waves on the ocean surface moving up and down around a flat, calm water level—the top of a wave is called the crest, and the bottom is the trough. Wavelength is the distance from one crest to the next crest (or from one trough to the next trough), while amplitude is how high the wave rises from the rest level to the crest (or how deep it drops to the trough). So, the term for the lowest point is trough.
