Its physics is most easily understood by considering the radiation in a cavity with rigid opaque walls. Motion of the walls can affect the radiation. If the walls are not opaque, then the thermodynamic equilibrium is not isolated. It is of interest to explain how the thermodynamic equilibrium is attain…

WebBlackbody Radiation. "Blackbody radiation" or "cavity radiation" refers to an object or system which absorbs all radiation incident upon it and re-radiates energy which is characteristic of this radiating system only, not dependent upon the type of radiation which is incident upon it. The radiated energy can be considered to be produced by ... WebTHERMAL RADIATION SUMMARY (Rees Chapter 2) Planck's Law describes the amplitude of radiation emitted (i.e., spectral radiance) from a black body. It is generally provided in one of two forms; Lλ(λ) is the radiance per unit wavelength as a function of wavelength λ and Lν(ν) is the radiance per unit frequency as a function of frequency ν. The first form is

WebA blackbody is an idealized object absorbing all incident electromagnetic radiation, regardless of frequency or angle of incidence. Consequently, it absorbs all colors of light as well and thus appears completely black. A blackbody in thermal equilibrium (at a constant temperature) emits electromagnetic blackbody radiation.
