Hi. I'm preparing a research proposal for class and I've finally decided to do variations on the double slit experiment. What I'm looking at doing is performing the basic experiment using a red laser, just so I can make sure I have a good understanding of how to do it. Then I think I will test the effects of infrared light, radio waves, and ultraviolet light rays. My physics teacher suggested experimenting also with an electromagnetic field underneath the light to see any effects that may have. I'm not sure on what he was thinking for the electromagnetic field because I thought light wasn't effected by something magnetic. Also, most importantly I need to know if its possible to focus a radio wave and pass it through the slit. Any help or ideas on what other variations I could do would be much appreciated.
