Blackbody radiation is described by Planck's equation† where the values of the constants are given in Appendix C. The spectral sterance [radiance] as a function of absolute temperature and wavelength is given as (4-1)L(λ)=(2hc2/λ5)(exp(hc/λkT)−1)−1[W m−3sr−1], ...

I’m not sure you understand absorptivity. If you did, then I don’t think you would have the problems you have with emissivity. The Planck equation was derived for a blackbody. A blackbody by definition has an emissivity identical to one and transmissivity and reflectivity identical to zero....

(1890). His works on the thermodynamic theory of radiation, which led to the se-miempirical establishment of the formula for the energy distribution in the electromagnetic spectrum of a blackbody (Planck’s radiation law), were of major importance. Planck presented this formula at a meeting of...
In this short note we mathematically derive Planck's Formula for blackbody radiation in Quantum Physics. This derivation shows that under certain plausible assumptions Planck's Formula is an exact mathematical identity that describes the interaction of energy. Furthermore, these assumptions are well just...
This led to the correct equation for the black-body radiation curve. The texts claim the use of discrete values was a "mathematical expedient" to reduce the computational load. This reason doesn't make sense to me, as the continuous solution could have been computed by the fairly simple inte...
