<P> When the electrons in the atom are excited , for example by being heated , the additional energy pushes the electrons to higher energy orbitals . When the electrons fall back down and leave the excited state , energy is re-emitted in the form of a photon . The wavelength ( or equivalently , frequency ) of the photon is determined by the difference in energy between the two states . These emitted photons form the element 's spectrum . </P>
