"A black body or blackbody is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. The name "black body" is given because it absorbs all colors of light. A black body also emits black-body radiation. In contrast, a white body is one with a "rough surface that reflects all incident rays completely and uniformly in all directions." " - Blackbody energy equation

WebWien's Displacement Law. For a blackbody radiator, the temperature can be found from the wavelength at which the radiation curve peaks. Discussion. If the temperature is = C = K, then the wavelength at which the radiation curve peaks is: λ peak = x10^ m = nm = microns. This wavelength corresponds to quantum energy. hν = x 10^ eV. http://hyperphysics.phy-astr.gsu.edu/hbase/wien.html
