1. Calculate the wave number for the longest wavelength transition in the Balmer series of atomic hydrogen. (RH 109677 cm-1)
2. What is the energy in joules, required to shift the electron of the hydrogen atom from the first Bohr orbit to the fifth Bohr orbit and what is the wavelength of the light emitted when the electron returns to the ground state? The ground state electron energy is -2.18 * 10-11 ergs.
