Explanation
Polarization restricts wave vibration to one plane. Only transverse waves can be polarized – this proves light is transverse (sound cannot be polarized as its longitudinal).
Polaroid filters allow only one vibration direction through. Cross two polaroids and no light passes. Polarized sunglasses reduce glare by blocking horizontally polarized reflected light.
LCD screens use polarized light – liquid crystals rotate polarization, controlled by voltage. 3D movies use different polarizations for each eye.
