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. Longitudinal waves also have two parts: compression, which are areas of high molecular density, and rarefactions, which are areas of low molecular density. Continue Reading.
1 For a sine wave, the wave height H is twice the amplitude 2  : For a periodic wave it is simply the difference between the maximum and minimum of the surface elevation z = Î· (x â c p t): Significant wave height H 1/3, or H s or H sig, in the time domain, is defined as the average height of the one-third part of the measured wavesâwhich are N in numberâhaving the largest wave heights:
