An electron (mass m) is contained in a cubical box ofwidths Lx = Ly =Lz = L. It emits and absorbs light bymaking transitions among the lowest five energy levels.(a) How many different frequencies of light couldthe electron emit or absorb if it makes a transition between a pairof the lowest five energy levels? What multiple ofh/8mL2 gives the (b)lowest, (c) second lowest, (d)third lowest, (e) highest, (f)second highest, and (g) third highestfrequency?
