Question

Stefan boltzmann law of blackbody radiation

Answer 1

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 energyradiated per unit surface area of a black bodyacross all wavelengths per unit time {\displaystyle j^{\star }} (also known as the black-body radiant emittance) is directly proportional to the fourth power of the black body's thermodynamic temperature T:

Answer 2

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.
