  1. Light and electrons’ wave nature Day 8

  2. Light acting as a wave prlo.aps.org olympusmicro.com

  3. Young’s Double Slit experiment • Take a laser, shine it at a plate with two thin slits, observe the interference pattern

  4. The electron equivalent • Shoot electron at a double slit or a lattice, with is like a slit • Examine what happens

  5. Davidson-Germer Experiment • That’s not what Davidson and Germer wanted to do • Wanted to examine the surface of nickel by observing how electrons bounced off it • Accidently provided strong evidence for deBroglie’s hypothesis that all matter has wave properties • http://phet.colorado.edu/en/simulation/davisson-germer

  6. Discussion • What’s similar about the Davidson-Germer experiment and the double slit experiment? • What’s different?
