... Parts of a Wave • Wavelength is the length of a wave from one location to the same location in the next wave…crest to crest for example. • Amplitude is the vertical distance from origin to crest or origin to trough. • The trough is the ‘bottom-point’ of a wave and the crest is the ‘peak’ of a wave. ...
