Kirchhoff's law of thermal radiation:For a body of any arbitrary material, emitting and absorbing thermal electromagnetic radiation at every wavelength in thermodynamic equilibrium, the ratio of its emissive power to its dimensionlesscoefficient of absorptionis equal to a universal function only of radiative wavelength and temperature, the perfect black-body emissive power
