Definition frequency physics
Webhertz, unit of frequency. The number of hertz (abbreviated Hz) equals the number of cycles per second. The frequency of any phenomenon with regular periodic variations can be expressed in hertz, but the term is used most frequently in connection with alternating electric currents, electromagnetic waves (light, radar, etc.), and sound. WebApr 7, 2024 · This sharp frequency definition, Hu says, is remarkable for a magnetic system, and the linewidth is 1000 times smaller than that of the best alternative microwave sources based on magnetic technologies. (Nonmagnetic sources often have superior properties but usually require low temperatures.)

It is also occasionally referred to as temporal frequency for clarity, and is distinct from angular frequency. Frequency is measured in hertz (Hz) which is equal to one event per second. The period is the interval of time between events, so the period is the reciprocal of the frequency.
