Waves

Waves: a disturbance or oscillation that travels through space and matter, accompanied by a transfer of energy. In other words, a wave is basically a transfer of energy that is generated from different oscillations or disturbances that travels through space and matter.
The picture above, although it is hard to see, is an example of some waves on the north shore. The different parts of the wave are the trough: which is the bottom of the wave, the crest: which is the top of the wave, wavelength: which is the distance between the two crests, amplitude: which is the distance from the trough to the crest. The wavelength and amplitude are used to measure the size of the waves for surf advisories.
