λ= = c f mL c hn n fi 8 2 22 di . We evaluate this expression for n i = 1 and n f = 2, 3, 4, and 5, in turn. We use h = 6.626 × 10 – 34 J · s, m = 9.109 × 10 – 31 kg, and L = 250 × 10 – 12 m, and obtain the following results: (a) 6.87 × 10 – 8 m for n f = 2, (the longest wavelength). (b) 2.58 × 10 – 8 m for n f = 3, (the second longest wavelength). (c) 1.37 × 10 – 8 m for n f = 4, (the third longest wavelength). 10. The energy levels are given by
