Question
which of the following is not true if stimulated emission occurs?
009 10.0 points An electron in an atom is in an excited state. It can give up some energy as light and make a transition back to the ground state. The transition occurs at a random time and the energy of photon given of corresponds to the energy between the excited state and the ground state. This process is known as spontaneous emission. There is a second way the electron can make a transition back to the ground state if there is a photon interacting with the atom. This process is known as stimulated emission. Which of the following is NOT true if stimulated emission occurs? 1. The emitted photon is identical but travels in the opposite direction to the incident photon. 2. The emitted photon is identical to the incident photon. 3. The incident photon must have the same energy as the difference in energy between the excited and ground states. 4. The electron must be in the excited state when the photon is incident on the atom.Explanation / Answer
1 option is not true. Emtted photon moves in the same direction as incident photon.
