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 ... WebStefan-Boltzmann law, statement that the total radiant heat power emitted from a surface is proportional to the fourth power of its absolute temperature.
