Frequency (symbol f ), most often measured in hertz (symbol: Hz), is the number of occurrences of a repeating event per unit of time. [1] . It is also occasionally referred to as temporal frequency for clarity and to distinguish it from spatial frequency.

- What is frequency in physics?In physics, the term frequency refers to the number of waves that pass a fixed point in unit time. It also describes the number of cycles or vibrat...
- What is the symbol of frequency?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...
- How is frequency expressed?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...

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.

May 3, 2019 · Learn what frequency means in science, especially in physics and chemistry, where it applies to waves. Find out how to measure frequency in Hertz and see examples of frequency in different contexts.
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.
