WebStefan-Boltzmann law. The Stefan-Boltzmann law, also known as Stefan's Law, is a law that expresses the total power per unit surface area (otherwise known as the intensity) that is radiated by an object, often taken to be a blackbody. [1] The formula used to determine at what wavelength the power peaks at is Wien's Law.
