Consider the H atom. Use eV for energies and show your calculation.
a.) Calculate the energies of the first four levels of the atom.
b.) What are the energies of each photon emitted in the first three lines of the Lyman series?
c.) What energy is required to ionize a atom in the ground state?
d.) What is the energy difference between the ionization energy and the energy of a Lyman-a photon?
