A hydrogen atom in a state having a binding energy (the energy required to remove an electron) of 0.85 eV makes a transition to a state with an excitation energy (the difference between the energy of the state and that of the ground state) of 10.2 eV.
(a) What is the energy of the photon emitted as a result of the transition? What are the
(b) Higher quantum number and
(c) Lower quantum number of the transition producing this emission?
