The Stefan-Boltzmann constant, symbolized by the lowercase Greek letter sigma ( ), is a physical constant involving black body radiation.
A black body, also called an ideal radiator, is an object that radiates or absorbs energy with perfect efficiency at all electromagnetic wavelength s.
The constant defines the power per unit area emitted by a black body as a function of its thermodynamic temperature.
Hence, Stephen constant does not depend upon wavelength of radiation.
