The electron of a hydrogen atom is in the n = 6 energy level.
(a) What is the energy, in units of eV, and the wavelength, in units of nanometres, of the highest energy photon emitted when this atom relaxes?
(b) What is the energy, in units of eV, and the wavelength, in units of nanometres, of the lowest energy photon emitted when this atom relaxes?
