I would like to discuss partial reflection of the photons and how thickness of the material (let's say glass) affects reflection (originally from Feynman, QED).
Let's say we have a glass 1m apart from the detector, and another glass 100m apart. The thickness of second glass affects probability waves and the percentage of the light reflected. I find this paradoxical. Let's say we shoot some photons to the glass. It takes 1m/c + 1m/c time to detect reflection from the first glass (highest probability wave peak).
My question is, how after 2m/c time we can know if there is another glass 100m apart? That's kinda FTL.
