Solved: (a) Calculate the energies of an electron in the
Chapter 3, Problem 39E(choose chapter or problem)
The visible emission lines observed by Balmer all involved nf = 2.
(a) Explain why only the lines with nf = 2 were observed in the visible region of the electromagnetic spectrum.
(b) Calculate the wavelengths of the first three lines in the Balmer series—those for which ni = 3,4 and 5—and identify these lines in the emission spectrum shown in Figure 6.11.
