Properties of a wave

• 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 and the unit of frequency is the Hertz, where one Hertz equals one wave per second.
• The period of a wave is the time in seconds for one wave to pass a point, which is calculated using the equation: period in seconds equals one divided by the frequency in Hertz.
