On the Double Slit Experiment
Most recent answer: 12/13/2012
Q:
Please read carefully.
If we perform the double split experiment by shouting photons covering one hole at a time, would we see equally the double split inference?.
That is, the same set up of double split but fire photons each time covering alternatively the holes.
Has somebody really tested it, not a variation of it?
Simply that.
Thank you very much.

A:
This is easy enough to do yourself. Take a double-slit, which you can make using a razor blade and a piece of aluminum foil. Or maybe you could use a glass slide with a layer of black paint, scratching slits in the paint. (In our lecture equipment we have thin metal disks, covered with black anodization, with milled slits.) You can use a red laser pointer for a light source. Mount everything so it doesn't shift around too much.
What you'll find is that when one slit is covered, you;ll get a single-slit pattern. When the other slit is covered, you'll get a slightly shifted single-slit pattern. When they're both open, you'll get a two-slit pattern, which isn't the sum of the two one-sit patterns.
