Unit Hz
Name hertz
Category Frequency
Details Hertz (Hz) is the unit of frequency in the International System of Units (SI). It is used to measure the number of cycles per second of a periodic event, such as the oscillation of a wave, an electrical current, or a sound wave. One Hertz (1 Hz) represents one complete cycle of a repeating event occurring in one second. In other words, if a wave or an electrical signal oscillates at a frequency of 1 Hz, it means it completes one full cycle every second. The unit is named in honor of the German physicist Heinrich Hertz, who made significant contributions to the field of electromagnetism.
