A wave equation

• The amplitude of a wave is the maximum displacement of a point on a wave away from its undisturbed position
• The wavelength of a wave is the distance from a point on one wave to the equivalent point on the adjacent wave.
• The frequency of a wave is the number of waves passing a point each second.
• The wave speed is the speed at which the energy is transferred (or the wave moves) through the medium.
• wave speed, v, in metres per second* m/s frequency, f, in hertz Hz *wavelength, λ, in metres, m
