The Stefan Boltzmann Law is a means of determining total energy radiated by any object, based entirely on its temperature.

This law states that the energy radiated from a black body is proportional to the fourth power of the absolute temperature. A black body is one which absorbs and emits radiation at all frequencies, with characteristic continuous emission spectra.

Formula:

J={\sigma}T^4

The terms

❂ J - Energy radiated per unit area of a black body per unit time [Units: J m-2 s-1]

❂ \sigma - Stefan-Boltzmann constant [Value: 5.67 x 10-8 J s-1 m-2 K-4]

❂ T - Absolute temperature [Units: K]

Answer:

The Stefan-Boltzmann law: The rate of emission

of radiant energy per unit area or the power radi-

ated per unit area of a perfect blackbody is directly

proportional to the fourth power of its absolute

temperature. OR

The quantity of radiant energy emitted by a

perfect blackbody per unit time per unit surface

area of the body is directly proportional to the

fourth power of its absolute temperature.
