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.

The great majority of waves one sees on an ocean beach result from distant winds. Three factors influence the formation of wind waves: Windspeed; length of time the wind has blown over a given area; and distance of open water that the wind has blown over (called fetch).
