Any process that is repetitive or periodic has an associated frequency. The frequency is the number of repetitions, or cycles, during a given time interval. The inverse of the frequency is called the period of the process. Pendulums, as in a...

Number of waves that pass a fixed point per unit time; also, the number of cycles or vibrations undergone in unit time by a body in periodic motion. Frequency &math.f; is the reciprocal of the time &math.T; taken to complete one cycle (the period), or...

n. The quantity representing the number of complete cycles (sense 1) (oscillations) performed by a given wave per unit time, commonly expressed in Hertz (Hz) and represented by the symbol f. For example, a vibrating violin string that is making 400...

The term frequency is encountered in everyday talk with reference to the number of times that something repeats or recurs; in PSYCHOPHYSICS, frequency is used to indicate the number of vibrations of cycles per unit time—it typically refers to the...

The number of complete cycles in a wave’s motion that pass a given point per unit of time. For the higher-frequency energy types the unit of measurement is the HERTZ (symbol Hz) with 1 Hz equating to 1 cycle per second. See also:...

The number of occurrences of the same score in a sample or a...

Sinusoidal waves of various frequencies; the bottom waves have higher frequencies than those above. Frequency is a measure of the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency. if...
