An electron (mass m) is contained in a cubical box of widths Lx = Ly = Lz = L. It emits and absorbs light by making transitions among the lowest five energy levels. (a) How many different frequencies of light could the electron emit or absorb if it makes a transition between a pair of the lowest five energy levels? What multiple of h/8mL2 gives the (b) lowest, (c) second lowest, (d) third lowest, (e) highest, (f) second highest, and (g) third highest frequency? (a) Number Units none
