Question

Quizplus · Accepted Answer

The polarization axes of glasses for 3-D viewing are at right angles to each other. This is because the two lenses in the glasses are polarized in different directions so that each eye sees a slightly different image, which creates the illusion of depth and three-dimensionality. If the polarization axes were either vertical or horizontal, the glasses would not be able to create this effect.
