A Diffraction Experiment with Electrons

However, if they are really particles, it is hard to see how they can be diffracted. Consider what happens when slit b is closed. Then all the electrons striking the screen must have come through slit a. We observe the result to be a single area of light on the screen (Fig. 1-1 lb). Closing slit a and opening b gives a similar (but displaced)
