Exahertz
EHz
Definition
The Exahertz is a unit of frequency equal to 10^18 hertz, representing extremely high frequencies in the electromagnetic spectrum. It is used in advanced physics research and theoretical studies of high-energy phenomena, particularly in particle physics and cosmology where frequencies approach the limits of current scientific understanding.
History/Origin
The exahertz unit was introduced as part of the SI system of prefixes to handle extremely large frequency values encountered in modern physics research. It represents frequencies that are 18 orders of magnitude higher than the base hertz unit, corresponding to wavelengths in the attometer range and energies in the petaelectronvolt range.
Current Use
Primarily used in theoretical physics, particle physics research, and cosmology for describing extremely high-frequency electromagnetic radiation. It is relevant in studies of gamma-ray bursts, high-energy cosmic rays, and theoretical models of the early universe where such extreme frequencies may have existed.

Hertz
Hz
Definition
The Hertz is the SI base unit of frequency, representing one cycle per second. It is named after Heinrich Hertz, a German physicist who made important contributions to the study of electromagnetic waves. The hertz is used to measure the frequency of periodic phenomena in physics, electronics, and telecommunications.
History/Origin
The hertz was adopted as the SI unit of frequency in 1960, replacing the older unit "cycles per second." It was named after Heinrich Hertz (1857-1894), who was the first to conclusively prove the existence of electromagnetic waves. Hertz's experiments in the 1880s demonstrated that electromagnetic waves could be generated and detected, laying the foundation for radio technology.
Current Use
Widely used in electronics, telecommunications, radio broadcasting, computer processors, and scientific research. It measures the frequency of alternating current, radio waves, sound waves, and other periodic phenomena. Essential for understanding resonance, harmonics, and wave behavior in various physical systems.
