I have read this question:
where PhysicsDave says:
All photons passing thru the slits leave a dot on the screen, this is true for single or multiple photon intensities. Destructive interference is a violation of conservation of energy, destructive interference is best explained by QM, there is low probability of photons arriving in the dark areas and that is why the dark areas are dark.
Now there are two opinions on this site:
When a single photon is shot, it passes through both slits as a wave and the partial waves of the photon interfere with each other, and create constructive (bright area) or destructive (dark area) interference.
Each and every single photon shot leaves a spot on the screen in the bright areas, there is a low probability for a photon to land in the dark area
These are two different meanings. One says that some photons never reach the screen, and never interact with the screen, that is why we see dark areas.
The other one says, that each and every single photon shot will leave a dot on the screen in the bright areas, and it is just that there is low probability for the photons to arrive in the dark areas, that is why we see dark areas.
Which one is right? Does every single photon shot leave a dot on the screen in the bright area?
