So I'm curious. When in one instance where light behaves as a wave and you get an interference pattern, and in another instance where light behaves as a particle and you don't, does the intensity of the inner most bands of light change at all? When we place a detector beside one of the slits and measure the particle, does that do anything to change the intensity of the two inner most bands of light? Lets say we have 2000 photons and fire 1000 photons each in two experiments, one with a detector and one without. You would think that when light is more scattered in the interference pattern there would be less intensity across the two inner most bands, as we have a limit of 1000 photons and maybe only 400 photons landed in either of those two inner bands. However when we place the detector next to the slit and light behaves as a particle, the intensity of light should be greater because there is no interference and thus all 1000 particles landed in those two inner bands. Is this the case? Can anyone shed any light (no pun intended!) on these types of observations? Thanks in advance!
