a. A household lightbulb is a blackbody radiator. Many light bulbs use tungsten filaments that are heated by electric current. What temperature is needed so that ?max=550nm?

b. Using the Rydberg formula, calculate values for the frequencies of the photons associated with the atomic hydrogen emission lines in the Lyman series(k=1) for: n=2,3,10,100 and infinity. Expressing your answer in terms of R. Note how the frequency converges to a limiting value; this value is called the series limit. WHat is the energy of a photon associated with the series limit of the Lymann series?
