An electron is dropping from a higher to a lower energy level with the difference in energy between the two being emitted as light. D. A proton is undergoing a nuclear change in the nucleus and is emitting a high energy light wave in the process. E. An electron is jumping from a low energy state to a high energy state with the difference in energy being converted to light.
