Wavelength The distance between two corresponding points (crest to crest, trough to trough)
Frequency The number of complete waves that pass a given point in a certain amount of time.
Speed How far a wave travels in a given amount of time.

Trough the low point of a wave
Resting position position the wave that would sit with no disturbance
