Hi All,
I am trying too undestand the slit test which shows wave-particle duality. Please correct me if I am wrong on the basic info on the test. One photon is shot out and if there is one slit it will go through the slit and make a point on the detection medium behind the slit. However if both slits are open then there will be an interference pattern which suggests hat the photon has gone through both slits.
Here are my questions. How is it actually done to insure beyond any doubt that only one photon has been released. Also what happens to the photon after it strikes the detection medium. Third question is how do we KNOW that if an individual photon is out there that it will be detected. My understanding is this is done in a dark room but how do we know that thre aren't stray photons or other particles in the room which could interact with the detection medium in a way that makes the interferene pattern.
Thanks,
Logician
