Black-body radiation
On the same graph, sketch the energy density of black body radiation u(ω) vs. the frequency ω for the two temperatures T and 2T. (Do not change the axes so that the two curves become identical.) The graph should be large-filling the page, so that details can be seen. Small graphs are not acceptable.
