i am a year 12 student and as i was reading a book written by Brain Clegg, i hit a roadblock. It would be great if somone could help me out with this.
when we conduct young's double slit experiment with a single photon , it is seen that we get an interference pattern due to the probability of the photon passing through either of the slits. Now, if we were to place a detector before the slits, we would know for sure through which slit the photon would pass. In the experiment does the results still show an interference pattern even though we know the location of the photon or does it disappear? And is the interference pattern still produced without a detector?
