The Stefan-Boltzmann Law describes the power radiated from a black body in terms of its temperature. Specifically, the Stefan-Boltzmann law states that the total energy radiated per unit surface area of a black body across all wavelengths per uni time, `j^("*")`, is directly proportional to the fourth power of the black body's thermodynamic temperature. To find the total power radiated from an object, multiply by its surface area:
`P=AepsilonsigmaT^4`, where:

• `A` = Surface Area
• `epsilon` = emissivity of the surface
• `sigma` = Boltzmann constant
• `T` = absolute temperature
