- 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 · Updated on May 03, 2019. In the most general sense, frequency is defined as the number of times an event occurs per unit of time. In physics and chemistry, the term frequency is most often applied to waves, including light, sound, and radio.
