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 ... WebQuantitatively, Wien’s law reads. λ max T = 2.898 × 10 −3 m · K. 6.1. where λ max is the position of the maximum in the radiation curve. In other words, λ max is the wavelength at which a blackbody radiates most strongly at a given temperature T. Note that in Equation 6.1, the temperature is in kelvins.
