About Hertz

Hertz (Hz) is the SI unit of frequency, measuring cycles per second, used for periodic events like sound, light, and electromagnetic waves, named after physicist Heinrich Hertz. One hertz means one cycle (or oscillation) occurs every second, commonly expressed in kilohertz (kHz), megahertz (MHz), or gigahertz (GHz) for higher frequencies, vital in electronics, telecommunications, and computing.
