The abbreviation for the units of measure of wavelengths of light is "nm" which stands for nanometers.
The unit of measuring wavelength of light is typically in nanometers (nm). One nanometer is equal to one billionth of a meter, making it a convenient unit for measuring the very small wavelengths of light.
The different optical power units used to measure the intensity of light in optical systems are diopters and watts. Diopters measure the refractive power of a lens, while watts measure the total power of light emitted or transmitted through a system.
W
A light meter is typically used to measure light intensity. These devices capture the amount of light in a particular area and provide a quantitative measurement in units such as lux or foot-candles.
Wavelength of red light is about 700 nanometers. ie 700 x 10 to the minus 9 meters. You may also come across units called Angstroms for light wavelengths-these were current when I was a physics student but went out of fashion. 1 Angstrom = 1/10 nm
Among the units of measure, "cc" is the abbreviation for cubic centimeter.
An SI unit is a unit of measure from the International System of Units. SI is the abbreviation for the French Système international d'unités
They measure them in light-years.
Hertz is a measurement of wavelength. It is the number of cycles in a second. You can also measure wavelength by the length of the wave moving at the speed of light. 3.5 MHZ (Mega Hertz) is about 80 meters long.
SI (French abbreviation for "International System") is, in English, the metric system. So the standard measure in SI is the meter.
The unit of measuring wavelength of light is typically in nanometers (nm). One nanometer is equal to one billionth of a meter, making it a convenient unit for measuring the very small wavelengths of light.
UNITS
Wavelength is the distance between repeating units of a propagating wave of a given frequency. For light waves, this value is often given in nanometers, abbreviated as "nm". A nanometer is 0.000000001 meters.

SI means "International System [of Units]" (from the French abbreviation).
