Stefan-Boltzmann Law

The Stefan-Boltzmann law states that the emissive power, P, from a black body is directly proportional to the forth power of its absolute temperature i.e.

P = T

where is the Stefan-Boltzmann constant

= 5.67E-8 W/(m K)

The emitted power, P, for a non-black body with emissivity, , is:
