The wavelengths of light emitted by an excited atom are determined by the:
differences in energy between the excited states and ground state
addition of the energies of the excited states and ground state
multiplication of the energy of the excited states by the energy of the ground state
division of the energy of the excited states by the energy of the ground state
differences in energy between the excited states and ground state
addition of the energies of the excited states and ground state
multiplication of the energy of the excited states by the energy of the ground state
division of the energy of the excited states by the energy of the ground state
