Hi, I'm struggling to conceptually understand why Brewster's angle occurs. I know Fresnel's equations and can see that at some angle, the reflected parallel component goes to zero. What I don't understand is why this is conceptually happening. I understand that the material is made up of 'dipoles' and free charges which can absorb and deflect the wave, but I cannot see why the perpendicular component is not treated the same way as the parallel component. I don't see how they appear any differently to the material. If someone could provide some insight into this, that would be great. Thank you.
