Frequency—number of events per unit of time. Period—time it takes to complete one oscillation. For waves, these variables have the same basic meaning. However, it is helpful to word the definitions in a more specific way that applies directly to waves: Amplitude—distance between the resting position and the maximum displacement of the wave.
frequency. In physics, the number of crests of a wave that move past a given point in a given unit of time. The most common unit of frequency is the hertz ( Hz ), corresponding to one crest per second. The frequency of a wave can be calculated by dividing the speed of the wave by the wavelength.
