The greater the amplitude of a wave the more energy it carries. The wavelength of a wave is the distance from one crest to the next or from one trough to the next. The frequency of a wave is the number of wave crests passing a point in one second. The unit of frequency is the hertz (Hz). The speed of a wave is given by the equation: v = f x · v= wave speed · f= frequency · = wavelength 2 of 2
