(e) The highest frequency is, in units of h /8 mL 2 , 3.75 (2, 2 1,1). (f) The second highest frequency is, in units of h /8 mL 2 , 3.00 (2, 2 1,2) or (2, 1 1,1). (g) The third highest frequency is, in units of h /8 mL 2 , 2.25 (2, 1 1,2). 25. The energy levels are given by E h m n L n L h mL n n nn x x y y x y xy , =+ L N M M O Q P P L N M M O Q P P 22 2 2 2 2 2 2 2 88 4 where the substitutions L x = L and L y = 2 L were made. In units of h 2 /8 mL 2 , the energy levels are given by /4 + . The lowest five levels are E 1,1 = 1.25, E 1,2 = 2.00, E 1,3 = 3.25, E 2,1 = 4.25, and E 2,2 = E 1,4 = 5.00. It is clear that there are no other possible values for the energy less than 5. The frequency of the light emitted or absorbed when the electron goes from an initial state i to a final state f is f = ( E f E i )/ h , and in units of h /8 mL 2 is simply the difference in the values of
