White light is dispersed by a glass prism into the colors of the visible spectrum. The visible spectrum is the band of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light (or simply light).
The color temperature scale describes only the color of light emitted by a light source, which may actually be at a different (and often much lower) temperature. [ 1 ] [ 2 ] Color temperature has applications in lighting , [ 3 ] photography , [ 4 ] videography , [ 5 ] publishing , [ 6 ] manufacturing , [ 7 ] astrophysics , [ 8 ] and other fields.
Red arrows show that 5780 K black bodies have 501 nm peak wavelength and 63.3 MW/m 2 radiant exitance. Correlated color temperature (CCT, T cp) refers to the temperature of a Planckian radiator whose perceived color most closely resembles that of a given stimulus at the same brightness and under specified viewing conditions."

Longer-wavelength radiation such as visible light is nonionizing; the photons do not have sufficient energy to ionize atoms. Throughout most of the electromagnetic spectrum, spectroscopy can be used to separate waves of different frequencies, so that the intensity of the radiation can be measured as a function of frequency or wavelength.

The emission or reflectance spectrum of a color is the amount of light of each wavelength that it emits or reflects, in proportion to a given maximum, which has the value of 1 (100%). If the emission or reflectance spectrum of a color is either 0 (0%) or 1 (100%) across the entire visible spectrum, and it has no more than two transitions ...
A rainbow is a decomposition of white light into all of the spectral colors. Laser beams are monochromatic light, thereby exhibiting spectral colors. A spectral color is a color that is evoked by monochromatic light, i.e. either a spectral line with a single wavelength or frequency of light in the visible spectrum, or a relatively narrow spectral band (e.g. lasers).
