Double slit applet

A nice applet to illustrate the crazy double slit stuff we talked about today.  You can use photons, electrons, neutrons, and helium atoms, and even use multiple sources or vary the incident wavelength. Note the different modes - high intensity, single particles, and lasers. If you like, add a detector on one or both of the slits and watch the interference go away ... neat stuff.

Also, the actual experiment with single electrons!
