Answer 2

Light can be thought of as containing electric and magnetic fields, which we model with scientific theories collected and refined by Maxwell. These fields, Maxwell says, are directional. Light that has a specific direction to its fields is called polarised light, and you can make materials called polarisers that are nearly transparent to one direction and completely block the other direction. This science is fundamental to the LCD, the commonest sort of display screen on the planet.
