A NAME: ________________________________________________________________ 1. Which of the following phenomena could be explained by classical physics and did not require a quantum hypothesis in order to make theory agree with experiment? (a) Blackbody spectra (e) Atomic line spectra (b) Diffraction of light (f) (b) and (e) (c) Low-temperature heat capacity in perfect crystals (g) (a), (b), and (d) (d) The photoelectric effect (h) (c) and (d) 2. If a normalized wave packet Ψ is given as ! x , y , z , t ( ) = c n " n n = 1 # $ x , y , z ( ) e % iE n t / h , what is the probability that an experiment will cause the system to collapse to the specific stationary state j ? (a) Quantum mechanics does not allow you to know this probability (e) c j (b) One (f) | c j | 2 (c) < ψ j | H | ψ j > (g) (b) and (d) (d) c j * (h) Only Schrödinger's cat knows 3. Which of the following statements about the de Broglie wavelength λ are false ? (a) λ decreases as mass increases if velocity is constant (e) A particle that has zero velocity has an infinite de Broglie wavelength
