A. Compare the results of an electron double slit experiment to that of water and light waves. For each, say how, if at all, they are similar and different:

1. water waves:

2. light waves:

B. Suppose a beam of electrons is aimed at two slits in a slide placed in front of a screen. After a short time the screen looks like the one at the right. What evidence does the picture give that electrons act like particles? Like waves?
