1. The problem statement, all variables and given/known data A single electron with de Broglie wavelength [tex] \lambda[/tex] passes through a slit of width d = 2[tex]\lambda[/tex]. The electron can then strike a flourescent screen. What will be observed on the screen? a) A diffraction pattern b) A single flash has if the electron had moved in a straight line through the slit. c)A single flash that could occur anywhere on the screen. d)A single flash that would most likely occur where a corresponding diffraction pattern would have the highest intensity. 2. Relevant equations NONE 3. The attempt at a solution Since there is only a single electron, I dont think we will get a diffraction pattern. So my answer is b.
