noun
- 1. the rate at which something occurs or is repeated over a particular period of time or in a given sample: "an increase in the frequency of accidents due to increased overtime"
- 2. the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second: "different thicknesses of glass will absorb different frequencies of sound"
Frequency (symbol f), most often measured in hertz (symbol: Hz), is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as temporal frequency for clarity and to distinguish it from spatial frequency.
The meaning of FREQUENCY is the fact or condition of occurring frequently. How to use frequency in a sentence.
May 13, 2024 · frequency, in physics, the 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.

- The symbols most often used for frequency are f and the Greek letters nu (ν) and omega (ω). Nu is used more often when specifying electromagnetic w...
- Frequency is usually expressed in the hertz unit, abbreviated Hz. One kilohertz (kHz) is 1,000 Hz, and one megahertz (MHz) is 1,000,000 Hz. In spec...
Feb 13, 2024 · Frequency, often denoted by the symbol f and measured in hertz (Hz), serves as a crucial metric for quantifying how frequently a repeating event occurs within a defined time interval. The core formula to calculate frequency is straightforward: Frequency (f) = 1 / Time Period (T)

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.
the number of times something happens within a particular period, or the fact of something happening often or a large number or times: frequency of Complaints about the frequency of buses rose in the last year. the increasing frequency of terrorist attacks.
