Definition
A blackbody is an ideal thermal radiator that absorbs completely all incident radiation whatever the wavelength, the direction of incidence, or the polarization [1]. This radiator has, for any wavelength and any direction, the maximum spectral concentration of radiance for a thermal radiator in thermal equilibrium at a given temperature.
Blackbody radiation is radiant energy emitted by an ideal black surface (blackbody) whose spectral power distribution is only governed by its own temperature.
Blackbody color is the temperature of a true blackbody emitter which to the human eye is a close match to the color of an incandescent object, which is not a blackbody.
Blackbody locusis the locus of points in...
