The electron in a hydrogen atom can undergo a transition from n=1 to n=6, absorbing a photon with a wavelength of 94 nm. How much energy must be absorbed for this transition to occur? How does this transition show that the energy of a photon is quantized? How does this absorption begin to approximate the ionization energy of hydrogen?
