Quick Answer. Transverse waves have two parts: a crest, which is the highest point of the wave, and the trough, which is the lowest part of the wave.

Sea state describes the combination of sea (wind) waves and swell. Wave height (trough to crest) for both sea and swell refers to 'significant wave height' which represents the average height of the highest one-third of the waves. Some waves will be higher and some lower than the significant wave height. The probable maximum wave height can be up to twice the significant wave height.
