A little Physics experiment
We have all heard of the double slit experiment. Here is my demonstration of it done with a simple green laser. Using black insulation tape I create a thin slit (about 1mm wide) in front of the beam. Then mount a piece of wire about in the middle of the slit. As the laser is a pointer I can adjust the beam so the wire is directly over the beam. Pointing the laser at a wall gives a diffraction pattern at right angles to the original slit, hence a double slit experiment!
Now to work out how to do it with electrons?
