What is the direction (vertical or horizontal) of the transmission axis of Polaroid sunglasses? Give the physical reason for your answer.

  • PHYSICS - ,

    Sunglasses are vertically polarized. This enables them to greatly suppress or block obliquely reflected light ("glare") from horizontal surfaces like bodies of water or car hoods, which is mostly horizontally polarized.
