<strong>Modern</strong> <strong>Physics</strong> Quantum Mechanics Questions 1. Is light a wave or a particle? Explain. What about an electron? 2. How would de Broglie account for the fact that in the Bohr model (which remember was highly successful in predicting the spectral lines of hydrogen), the electrons are always found at certain distinct distances from the nucleus? 3. Why is the wave nature of matter not more apparent to us in our everyday lives? 4. In classical physics, the accuracy of measurements has always been limited by the measuring instruments used, and no instrument is perfect. How is this limitation different from that formulated by Heisenberg in the uncertainty principle? 5. What is the physical significance of the square of the Schroedinger wave function, |Ψ| 2 ? 103
6. Describe the quantum-mechanical model of the atom. How is this similar to Bohr’s model? How are the two different? 7. Sum up quantum mechanics and our current interpretations of quantum mechanics. Use Feynmann’s notes if you find them helpful. 104
