Grimaldi-type experiments

[androstan1234]

How do the popular Copenhagen and Path Integral interpretations of quantum explain the experiments on light by Grimaldi and later by Newton and Thomas Young?

 

In case you don't know, these were "zero slit" experiments, i.e. we remove the outer frame of the windows and leave only the center post. The post was often a thin wire or hair and was placed in a beam of light.

 

"All possible classical paths" in such a situation are directed outward, away from the post. We can't get a classical path wherein the photon lands directly behind the post.
