2. (10 points) The Planck blackbody distribution formula I(1) = 4tħc? [ / 21ħc 11 15 exp ket)-1|| in a sense, "began" quantum mechanics in 1900, in that it was the first time that what is now known as the Planck constant (h) was used in physics. Before Planck, however, Wilhelm Wien used purely classical thermodynamic arguments to motivate the empirical relation?. I(W) = exp (Home) from which he was able to “prove” two known observations. Specifically, these were the Wien displacement law: ImałT = (constant), and the relation between total radiative flux (the integral of I(1) over all wavelengths) and temperature: [ 1()d1 = (constant) T4. Do the corresponding derivations, and work out the analytic values of the two constants in terms of a, b, and Boltzmann's constant kb.
