Photons are emitted by atoms as electrons move from 4o her-energy outer orbits hi Brackett o lower-energ Inner Paschen orbits. The energy of an emitted photon is equal to WYVY the difference in energy Balmer senes between the two orbits Because an electron is restricted to discrete orbits only particular light n=1- frequencies are emittedPhotons are emitted by atoms as electrons move from higher-energy outer orbits to lower-energy inner orbits. The energy of an emitted photon is equal to the difference in energy between the two orbits. Because an electron is restricted to discrete orbits, only particular light frequencies are emitted
