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.

Gigahertz
GHz
Definition
The Gigahertz is a unit of frequency equal to 10^9 hertz, representing frequencies in the microwave and millimeter wave range of the electromagnetic spectrum. It is widely used in telecommunications, radar systems, and computer processors, corresponding to wavelengths in the centimeter to millimeter range.
History/Origin
The gigahertz unit became prominent with the development of microwave technology during World War II and the subsequent growth of radar and telecommunications systems. It represents frequencies that are 9 orders of magnitude higher than the base hertz unit, corresponding to wavelengths in the microwave region.
Current Use
Extensively used in wireless communications (WiFi, Bluetooth, cellular networks), radar systems, satellite communications, and computer processors. It is essential for understanding microwave oven operation, GPS systems, and the development of high-speed digital communication technologies.
