WebbAs the temperature of a blackbody increases, the total emitted power also increases. Quantitatively, Stefan’s law expresses this relation as P ( T) = σ A T 4 6.4 where A is the … WebbThe Stefan-Boltzmann Law. The first quantitative conjecture based on experimental observations was the Stefan-Boltzmann Law (1879) which states the total power (i.e., integrated over all emitting frequencies in Figure 1.1.3 ) radiated from one square meter of black surface goes as the fourth power of the absolute temperature (Figure 1.1.4 ): \[P = …
