Suppose that we have a light emission apparatus capable of emitting only one photon. Then we set this photon to pass in a double slit apparatus and emerge in a black screen such that when it is absorbed the photon lives a mark.
My question is: if we close one of the slits, and set a sufficiently large amount of photons perform the above apparatus what we will see in the screen is a normal distribution or a interference pattern? If we set light, instead of photons, we see an interference pattern, correct? But does the one-photon change, changes the way that the experiments shows itself, showing a more 'particle' than 'wave' characteristic of light?
