Accurate Quote by Richard P. Feynman
“Thus we can get the correct answer for the probability of partial reflection by imagining (falsely) that all reflection comes from only the front and back surfaces. In this intuitively easy analysis, the 'front surface' and 'back surface' arrows are mathematical constructions that give us the right answer, whereas … a more accurate representation of what is really going on: partial reflection is the scattering of light by electrons inside the glass.”

Source Lecture: Theoretical Physics, Richard Feynman, 1960s
Treating reflection as only from front and back surfaces simplifies calculation but hides the true scattering by electrons inside the material.
In simple terms: Simplify to front/back surfaces, but real reflection is electron scattering.
