# The Balmer series for the hydrogen atom corresponds to electronic transitions that terminate in the state with quantum number $n=2$ as shown in Figure P28.19. Consider the photon of longest wavelength corresponding to a transition shown in the figure. Determine (a) its energy and (b) its wavelength. Consider the spectral line of shortest wavelength corresponding to a transition shown in the figure. Find (c) its photon energy and (d) its wavelength. (e) What is the shortest possible wavelength in the Balmer series?

## a) 1.889 $\mathrm{cV}$b) 658 $\mathrm{nm}$c) 3.02 $\mathrm{eV}$d) 412 $\mathrm{nm}$e) 366 $\mathrm{nm}$
