Black body radiation problems and solutions
WebPlanck showed that the intensity of radiation emitted by a black body is given by B λ = c 1λ−5 exp(c 2/λT)−1 where c1 and c2 are constants c1 = 2πhc2 = 3.74×10−16Wm−2 and c2 = hc k = 1.44×10−2mK. The function Bλ is called the Planck function. For a derivation of the Planck function, see for example the WebA 10 cm cube of glass of refractive index 1.66 has a small object at its center.
