Best Answer

In electromagnetic waves -- or ocean waves, for that matter -- a crest is the peak, or maximum height, of the waveforms. A troughs is the lowest point. The wavelength of a wave is measured from one crest (peak) to the next or from one trough to the next.

The trough is the low point of a wave.
