PPT-Stefan-Boltzmann law governs the radiation of energy by a black body: M = {emissivity}

4 Emissivity is a constant so the energy radiated increases as the 4th power of temperature The sun T6000K emits vastly more energy than the earth at T300K The wavelength of maximum energy radiated by a body is given by .
