WebJan 5, 2024 · Therefore, the radiation field inside the black body is not a function of the shape and size. So long as it is evacuated and fully closed, it will continue to emit isotropic radiation, depending only on its temperature. Therefore, black body radiation strength is a function of T alone. WebMar 5, 2024 · Integration of Planck's equation to arrive at Stefan's law is a bit more tricky. It should be clear that ∫ 0 ∞ M λ d λ = ∫ 0 ∞ M ν d ν, and therefore I choose to integrate the easier of the functions, namely M ν. To integrate M λ, the first thing we would do anyway would be to make the substitution ν = c / λ. Planck's equation ...
