(a) Derive the blackbody Stefan-Boltzmann law (ie total flux is proportional to T 4) by integrating the above expression over all wavelengths. Thus show that. (b) Show that the maximum value of R ( ,T) occurs for m T = 2.898 * 10 -3 mK (this is called Wien's displacement law). WebThe derivation of the power law of Stefan [1879] and Boltzmann [1884] is presented in Section 5. It is shown that this power law is generally independent of the domain in which the Planck function is presented.
