Question

When a beam of unpolarised monochromatic light is incident on a plane glass plate at a polarizing angle, then which one of the following statements is correct?

Options

• Reflected and refracted rays are completely polarized with their planes of polarization perpendicular to each other.

• Reflected and refracted rays are completely polarized with their planes of polarization parallel to each other.

• Reflected light is partially polarized but refracted light is plane polarised.

• Reflected light is plane-polarized light but transmitted light is partially polarized.

Answer 1

Reflected light is plane-polarized light but transmitted light is partially polarized.
