Polarization (What is the linearly polarization wave? Give the definition of the optical activity phenomenon?)

POLARIZATION

Variant 1

1. What is the linearly polarization wave?
2. Give the definition of partially polarized light.
3. What is Polaroid?
4. Write down Malus law.
5. What is the extinction position?
6. When ordinary light (“white light”) is reflected from a transparent material such that the angle between the reflected and refracted beam is 90 degrees the reflected beam is linearly polarized. The direction of polarization is parallel to the interface. Some sunglasses are made from Polaroid sheet. How should the polarization direction be oriented to minimize the intensity of light reflected from such transparent material?
