Three-Dimensional Energy Well An electron (mass m) is contained in a cubical box of widths Lx= Ly= Lz.. The potential energy outside the box is assumed to be infinite.

(a) How many different frequencies of light could the electron emit or absorb if it makes a transition
between a pair of the lowest fiveenergy levels? Among your answers from (a), what multiple of h2/8mL2 gives the (b) lowest, (c) second lowest, (d) third lowest, (e) highest, (f) second highest, and (g) third highest frequency?
