Unformatted text preview: madrid (tmm2353) – HW 8-1 – Antoniewicz – (56445) 1 This print-out should have 14 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 5) 6.0 points Match the description of a process with the corresponding arrow in the figure below. E E 1 E 2 E 3 III II I IV Absorption of a photon whose energy is E 1- E . 1. Transition I correct 2. Transition IV 3. Transition III 4. Transition II Explanation: Absorption sends the atom into a higher energy state, so this arrow will point upward. Given that the amount of energy is repre- sented by the difference between E 1 and E , it should be clear that Transition I is correct. 002 (part 2 of 5) 6.0 points Absorption from an excited state (a rare event at low temperatures). 1. Transition III 2. Transition II 3. Transition IV correct 4. Transition I Explanation: Following the explanation from part 1, we know this arrow will point upward. The phrase “from an excited state” should indi- cate that the atom was already in an excited state, so Transition IV is the only possibility. 003 (part 3 of 5) 6.0 points Emission of a photon whose energy is E 3- E 1 . 1. Transition I 2. Transition III 3. Transition II correct 4. Transition IV Explanation: Emission sends the atom into a lower energy state, so the arrow must point downward. Transition II is correct. 004 (part 4 of 5) 6.0 points Emission of a photon whose energy is E 2- E . 1. Transition III correct 2. Transition IV 3. Transition I 4. Transition II Explanation: As in part 3, emission indicates that the arrow will point downward. Transition III is correct. 005 (part 5 of 5) 6.0 points In drawing arrows to represent energy tran- sitions, which of the following statements are correct? List all that apply, separated by commas. If none apply, enter “none”....
