1) An electron in the hydrogen atom drops from the n=5 level to the n=1 level. What are the frequency, wavelength, and energy of the emitted photon? In which series does this photon occur? How much energy must be absorbed by the atom in order to kick the electron back up to the fifth level?

2) Calculate the maximum wavelength for the initiation of a photoelectric current in the aluminum (work function W = 4.28 eV).
