Frequency is a measurement of how often a recurring event such as a wave occurs in a measured amount of time. One completion of the repeating pattern is called a cycle. Only moving waves which vary their positions with respect to time possess frequency. Frequency is one way to define how fast a wave moves.
The amplitude is the distance from the medium to the crest. The wavelength is the distance between crest to crest or from trough to trough. A wave also has a frequency. A frequency of a wave is the amount of waves that pass through a point in a certain amount of time. The frequency of waves is measured in hertz or Hz. In a wave speed, frequency, and wavelength are much related. For example to find the speed of a wave you have to multiply wavelength time's frequency.
