P7A.4 The wavelength λmax at which the Planck distribution is a maximum can be found by solving dp(AT)/d7-0. Differentiate ρα'T) with respect to T and show that the condition for the maximum can be expressed as xe 5(e-1) = 0, where x = hc/AKT. There are no analytical solutions to this equation, but a numerical approach gives x = 4.965 as a solution. Use this result to confirm Wien's law, that λmaxT is a constant, deduce an expression for the...
