What is the symbol of frequency?
The symbol of frequency is hertz.

Frequency is a physical quantity indicating the periodic motion speed of an object, such as rotation speed and vibration speed. Its unit is hertz, and its symbol is hertz. Every object has a frequency independent of amplitude, which is determined by the nature of the object itself and is called the natural frequency. The concept of frequency is often used not only in mechanics and optics, but also in quantum mechanics, electromagnetism and radio technology.

Definition of frequency:

The number of times a substance completes periodic changes in unit time is called frequency, which is often expressed by F.

In order to commemorate the contribution of German physicist Hertz, people named the unit of frequency Hertz, abbreviated as "Hertz", and the symbol was Hertz.

Frequency, that is, the number of times to complete periodic changes in time, is a quantity that describes the frequency of periodic motion. It is usually represented by the symbol F or V, with the unit of one second and the symbol s- 1.
