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.
