Question

Stefan boltzmann law of radiation

Answer 1

The Stefan–Boltzmann constant (also Stefan's constant), a physicalconstant denoted by the Greek letter σ (sigma), is theconstant of proportionality in the Stefan–Boltzmann law: "the total intensity radiated over all wavelengths increases as the temperature increases", of a black body which is proportional to the ...



hope I helped you

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.
