An isolated atom of a certain
element emits light of wavelength 512 nm when the atom falls from
its fifth excited state into its second excited state. The atom
emits a photon of wavelength 411 nm when it drops from its sixth
excited state into its second excited state. Find the wavelength of
the light radiated when the atom makes a transition from its sixth
to its fifth excited state.
