Question
Problem 5: Electrons on the surface of a metal can be ejected by shining light on them. However, a very bright red light source will not eject electrons, while even a very dim violet light source will eject electrons from the metal immediately. Why is this? Problem 6: Suppose you perform a double slit experiment with only a few hundred electrons. (a) Sketch what the pattern on the far screen would look like if electrons behaved purely like classical waves. (b) Sketch what the pattern on the far screen would look like if electrons behaved purely like classical particles. (c) Sketch what the pattern on the far screen actually looks like when this experiment is performed. Problem 7: Connect each of the following famous quantum experiments with its implication: Millikan oil drop experiment Double slit experiment (light) Double slit experiment (electrons) Photoelectric effect Light behaves like a wave Light behaves like a particle The electron behaves like a wave The electron behaves like a particle Problem 8: For optical microscopes, the smallest object you can see depends on the wavelength PreviousExplanation / Answer
Millikan oil drop experiment - Electron behaves like a particle.
Double slit experiment (light) - Light behaves like a wave.
Double slit experiment (electrons) - Electron behaves like a wave.
Photoelectric effect - Light behaves like a particle.
