Planck's Blackbody Distribution Law. A perfect emitter, also known as a blackbody, is a material that radiates 100% of the electromagnetic energy that is theoretically possible for a material at a specified temperature. Planck’s blackbody equation defines the intensity of radiation for a blackbody as a function of temperature and wavelength.

Substitution of this approximation into the Planck distribution immediately gives the Rayleigh-Jeans law. The Wien law may also be obtained from the Planck distribution. In this case we are looking for the position of the maximum in the distribution.

Planck's radiation law. The value of Planck’s constant is found to be 6.62606957 × 10 −34 joule∙second, with a standard uncertainty of 0.00000029 × 10 −34 joule∙second. For a blackbody at temperatures up to several hundred degrees, the majority of the radiation is in the infrared radiation region of the electromagnetic spectrum.
