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.
To describe a wave, you need to know a few of its properties. One property is its wavelength. For a sound wave, this corresponds to how high or how low a note sounds. For a light wave, it corresponds to the colour of light. Another property is the amplitude, which corresponds to loudness for a sound wave or brightness for a light wave. One of the basic characteristics of a wave is its wavelength. This is the distance from one peak, or crest, to the next.
