A blackbody radiator is a theoretical object that absorbs all incident electromagnetic radiation, regardless of wavelength. A perfect blackbody radiator would emit electromagnetic radiation with a spectral radiance that is uniform across all wavelengths, and its intensity would be proportional to the fourth power of its temperature. Real objects, however, are only poor blackbody radiators, … Read more
