Wavelength in Kilometres
km
Definition
The Wavelength in Kilometres is a unit of frequency equal to the frequency of electromagnetic radiation with a wavelength of one kilometre (10^3 meters). It represents low frequencies in the electromagnetic spectrum, corresponding to wavelengths that are 3 orders of magnitude larger than the base meter unit.
History/Origin
The wavelength in kilometres unit was established as part of the SI system to handle long wavelengths encountered in radio communications and cosmology. It represents frequencies that are 3 orders of magnitude lower than the base hertz unit, corresponding to wavelengths in the kilometre range.
Current Use
Used in radio communications, cosmology, and studies of the early universe where such long wavelengths may have existed. It is relevant for understanding the behavior of matter and energy under extreme conditions and for studying cosmic phenomena that produce low-frequency electromagnetic radiation.

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.
