Polarization of LightPolarization of Light is a light box with a polarizing
filter on the front. There is another filter that is mounted in front
of the fixed filter that can be rotated. In one position, the two
filters disagree and very little light gets through. Transparent objects
can alter the polarization of the light travelling through them, giving
a color effect. Molded plastic has strains frozen in that can be visualized this way.
