From this video of a Feynman lecture:
At 39:30 he (Feynman) draws a line from the eye to the mirror, and then continues the line through the mirror, to represent where the image appears to come from (it appears to come from behind the mirror). Here he is showing the classical way of thinking of a light ray. Here the angle of incidence and the angle of reflection are the same.
Now as he explains the quantum mechanical view, at 41:40 he draws a path located at the left side of the mirror, as one of many paths the light can take (one of many possible probability amplitude contributions).
He continues to draw more paths that the light might take, but now I have my question. If the light might have taken another path than from the center of the mirror (where angle of incidence and angle of reflection the same), it seems to me that the apparent position of where the light comes from, would be shifted, and therefore wouldn't that cause our view of the image to be fuzzy or blurry?
I hope my question is clear. I am not questioning the math of quantum mechanics. I understand that it is quite accurate. I just don’t see the logic in the interpretation of this particular example.
