Question

A certain quantum mechanical system has the energy levels shown in the accompanying diagram. The energy levels are indexed by a single quantum number n that is an integer. ( a ) As drawn, which quantum numbers are involved in the transition that requires the most energy? ( b ) Which quantum numbers are involved in the transition that requires the least energy? ( c ) Based on the drawing, put the following in order of increasing wavelength of the light absorbed or emitted dur - ing the transition: (i) n = 1 to n = 2 ; (ii) n = 3 to n = 2 ; (iii) n = 2 to n = 4 ; (iv) n = 3 to n = 1 . [Section 6.3] n = 4 n = 3 n = 2 n = 1
