frequency is a measurement which gives the number of times per second an event occurs. for example, in wave motion the frequency is given as the number of times a similar point (crest or trough) on the wave form passes by a stationary point in one second. the value for this measurement is called hertz, so if two repetitions of a wave pass a point in a second, the wave has a frequency of two hertz.

in physics, number of waves that pass a fixed point in unit time; also the number of cycles or vibrations undergone during one unit of time by a body in periodic motion (q.v.). A body in periodic motion is said to have undergone one cycle or one vibration after passing through a series of events or positions and returning to its original state.

If the period, or time interval, required to complete one cycle or vibration is 1/2 second, the frequency is 2 per second; if the period is 1/100 of an hour, the frequency is 100 per hour. In general, the frequency is the reciprocal of the period, or time interval—i.e., frequency = 1/period = 1/(time interval). The frequency with which the Moon revolves about the Earth is slightly more than 12 cycles per year; the frequency of the A string of a violin is 440 vibrations or cycles per second.

Frequency means cycles per second. When a prossess happens again and again then frequency is a nunmber which indicates that For hwo many times it is happening in one second

There are several definitions for frequency based on differing context. See Dictionary.com for a list and decide which you need to use.

is a measurement of events per time.
e.g. waves per second (measured in hertz (Hz))
