1. The problem statement, all variables and given/known data Derive Stefan-Boltzmann Law from Wien's Law. Hint: You can use (without proof) R(T)=∫(-∞ to ∞) R(λ,T)dλ, p(λ,T)= 4/c R(λ,T). 2. Relevant equations Stefan-Boltzmann Law:P=AσT^4 Wien's Law: λmax=(2.898*10^-3 m*K)/T. 3. The attempt at a solution Let λmax=(2.898*10^-3 m*K)/T. Using cross multiplication gives: T=(2.898*10^-3m*K)/λmax. Raising both sides to the fourth power gives: T^4=(2.898*10^-3m*K)^4/(λmax)^4. Multiplying both sides by λmax^4 gives: T^4*(λmax)^4=(2.898*10^-3m*K)^4. Im not really sure if this going to go anywhere. My idea was to just algebraically manipulate Wien's Law to equate to Stefan-Boltzmann Law. The issue I have with doing this is that I am not sure what the hint even means (physically).
