so I'm using my laptop outside while also wearing polarized sunglasses. I've only taken up thru physics 2 and it's the summer so ( ) and I'm not mentally on my A game so to speak. But I want to know if my impression here is close to correct or the real explanation if not. from certain angles and positions* relative to the screen portions of the glasses block the image on the screen completely, instead showing a reflexion on the screen (as though the computer were turned off). does this mean something about the polarization of the light that my laptop screen emits or is the answer somewhat different? If yes to the former, why would all the polarization be the same? *I'm talking about my head and when I speak of positions and my face when I refer to angles. In this post I'm only referring to instances in which removing the glasses would give me a clear view of the "black" spot.
