Polarization - JavaLab


Polarizers are made of long-chained molecules which absorb light with electric fields.

When you shine a light on a polarizer, only a part of the light is passed. The polarizing plate materials absorb only the electric field component of light having the same direction as themselves. The absorbed electric field is converted into heat energy. On the other hand, the electric field component perpendicular to the polarization direction passes through it.
