Derive stefan's law from planck's law
WebMay 22, 2024 · The Stefan–Boltzmann law determines the total blackbody emissive power, E b, which is the sum of the radiation emitted over all wavelengths. Planck’s law describes the spectrum of blackbody radiation, which depends only on the object’s temperature and relates the spectral blackbody emissive power, E bλ.
