This is an interaction in which two waves meet, matching the crest of one with the trough of the other. They cancel out, producing smaller crests or troughs than a single wave alone. The bending of a wave as it moves from one medium to another. This is a volume of space that is empty of matter. In a transverse wave, this is the magnitude of height of a wave from origin to crest. In a longitudinal wave, this is corresponds to how much the wave is compressed, as compared to areas of little compression. The bouncing back of a wave from a surface. This is the distance from the peak to a peak of a successive wave. This is an interaction in which two waves meet, matching crest to crest and trough to trough. The resultant wave will have an amplitude of the sum of the two. This is the increase in density of a medium due to wave travel. This is the transport of energy by ocean surface waves, and the capture of that energy to do useful work. This is the number of complete movements of a wave per second.
