An electron is in the n=5 state of a hydrogen (Bohr) atom. As it de-excites to the ground state, how many emission lines are possible? Show these on an energy level diagram. Which emission line has the shortest wavelength? Which emission line has the longest wavelength? (You do not need to actually find these wavelengths.)
