I was reading about the double slit experiment (it seems I always glean a better understanding every time I read, which shows how little I really get it in the first place), and I was wondering:
Is there some way for us to know that the photo that was fired (given a single photo experiment) is actually the SAME photo that hits the screen?
Perhaps I don't have a proper understanding of what photos are - if this is the case let me know.
But if I remember photons are absorbed and re-emitted all the time, right? Like light hits something and if it bumps and electron around then a photon is released?
If that is the case I don't see how you could say that the photon(s) that hit(s) the screen is/are actually the same one(s) that was/were fired if there are say... air particles, and and dust and whatever, not to mention some piece of plastic or metal to supply the slits...
Do I have a proper understanding? Close? Or do I totally not get it at all?
Thanks:)
