mean position wavelength displacement crest trough amplitude propagation

mean position click to hear : mean position

Horizontal line around which the wave oscillates, carrying energy.

wavelength click to hear : wavelength

Distance between two consecutive crests or troughs; it corresponds to the distance traveled by the wave over time (its period).

displacement click to hear : displacement

Gap in relation to the mean position.

crest click to hear : crest

Highest point of the wave.

trough click to hear : trough

Lowest point of the wave.

amplitude click to hear : amplitude

Maximum displacement of a wave in relation to its mean position; it corresponds to the amount of energy transmitted.

propagation click to hear : propagation
