I've been wondering about the implications of this experiment and have a couple of questions about variations that I'm wondering if anyone has done. (I did not find any examples of these variations elsewhere).
1) In this variation, you have the photon pass through the slits twice. First through a single slit, then through a double slit. My thought is that a single slit, according to my understanding of other experiments, causes the collapse of the wave function, "forcing" the photon to a particle. If it's a particle, then does it go through only 1 of the 2 remaining slits? Or does its wave form "reconstitute" and the same interference pattern is observed?
2) In this variation, a divider or barrier is placed between the two slits - thus theoretically preventing interference. In this case, is an interference pattern observed? Is any pattern observed?
Thanks for your thoughts.
