Stefan-Boltzmann Law

[Magdalena Palavecino 1A]

Can someone please explain the Stephan-Boltzmann law? I am having a hard time understanding how to use it and what it is supposed to tell us.

Stefan-Boltzmann law shows how the intensity of the radiation emitted by black body is related to its temperature (as it is heated up). You can find temperature knowing the intensity and vice versa using this formula.
Black body is a hypothetical object that absorbs all kinds of radiation. The discovery of this and Wien's law has proved that classical physics is no longer applicable to everything as was thought before.

The law states that the total heat energy/radiant energy from an object is in proportion with its absolute temperature, and it only applies to blackbodies [the ideal blackbody does not reflect any incoming light, but rather absorbs it]. With this equation, you can solve for total radiant heat energy or absolute energy (in kelvin) - regarding these black bodies, Dr. Lavelle said that we will not be tested over them.
