A hydrogen atom in a state having a binding energy (the energy required to remove an electron) of 0.378 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 12.750 eV. What is the energy of the photon emitted as a result of the transition? Answer in ev?
