A He+ ion is placed in an excited state, so that its remaining electron occupies the n=5 state. The electron can make a transition to any lower energy state, thereby giving off a photon. What wavelengths of light would be given off in these transitions? (Note: if the electron initially decays to, say, the n=3 state, it could further decay to lower states, giving off additional light. However, I am not asking you to calculate those secondary transitions.)
