What are 3D glasses made of?
Modern 3D glasses usually use circular polarized light, which doesn’t require the viewer to keep his head still while watching. To make these lenses at home, you would need one sheet of counterclockwise circular polarized plastic, and one sheet of clockwise polarized plastic (also called left- and right-handed).
What can we say about a polarizing filter with vertically aligned chemical molecules?
What can we say about a polarizing filter with vertically aligned chemical molecules? It will allow horizontally polarized light to pass through it.
What can we say about a polarizing filter?
Using a polarizing filter can increase color saturation in your images by reducing reflections from water, glass, leaves, and other non-metal surfaces. Polarizing your view of the sky will prevent randomized blue light from coming into your lens, leaving you with the purest blue light possible.
Which of these materials would result in horizontally polarized light?

What can we say about a polarizing filter with vertically aligned chemical molecules A It will allow vertically polarized light to pass through it B it will allow horizontally polarized light to pass through it c it will block unpolarized light D it will allow?
The polarizing filter converts the unpolarized light to the polarized light by allowing the light waves to flow only in one plane. When the polarizing filter is placed vertically, the vertical filter allows the vertical light rays to pass through it. Thus, Option-A is correct.
