Source sentences:
text: Likewise, through spontaneous emission, an electron in a higher energy state can drop to a lower energy state while radiating the excess energy as a photon.
text: For this to occur, the electron must drop to a lower energy state that has an energy difference matching the energy of the interacting photon.
