Unformatted text preview: madrid (tmm2353) HW 8-2 Antoniewicz (56445) 1 This print-out should have 16 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 7) 5.0 points Of the energy diagrams I-VII below, which is appropriate for each of the following situa- tions? 100 MeV (I) 1 MeV (II) . 0001 eV (III) (IV) (V) (VI) (VII) Coarse Structure Fine Structure Hadronic (such as + )? 1. II 2. V 3. I correct 4. VII 5. IV 6. None is appropriate 7. III 8. VI Explanation: The energy scale for a subatomic particle (10 8 eV) is much greater than for the atomic level (1 eV). Diagram I is best in this case. 002 (part 2 of 7) 5.0 points Vibrational states of a diatomic molecule such as O 2 ? 1. III 2. VII 3. VI 4. None is appropriate 5. V 6. I 7. IV correct 8. II Explanation: This is similar to the typical energy between two atoms. Diagram IV is the best choice. 003 (part 3 of 7) 4.0 points Idealized quantized spring-mass oscillator? 1. VI 2. IV 3. III 4. V correct madrid (tmm2353) HW 8-2 Antoniewicz (56445) 2 5. None is appropriate 6. II 7. VII 8. I Explanation: A harmonic oscillator has equally spaced energy levels. This is best shown by Diagram V. 004 (part 4 of 7) 4.0 points Nuclear (such as the nucleus of a carbon atom)? 1. IV 2. None is appropriate 3. VI 4. V 5. I 6. III 7. II correct 8. VII Explanation: Nuclear excitations are on the order of about 1 MeV = 10 6 eV. This is best given in Diagram II. 005 (part 5 of 7) 4.0 points Electronic, vibrational, and rotational states of a diatomic molecule such as O 2 ? 1. None is appropriate 2. I 3. V 4. III 5. IV 6. VII correct 7. II 8. VI Explanation: This would be given by the splitting of elec- tronic levels due to vibrational and rotational states. Diagram VII is the correct choice. 006 (part 6 of 7) 4.0 points Rotational states of a diatomic molecule such as O 2 ? 1. I 2. V 3. II 4. VII 5. IV 6. None is appropriate 7. III correct 8. VI Explanation: This is the scale of energy for rotational states. Diagram III is correct....
