Assertion : When light ray is incident at polarising angle on glass, refracted light is partially polarised. Reason : The intensity of light decreases in polarisation.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

D. If both assertion and reason are false.

Step-by-step solution

(d) : Light reflected (in the rarer medium) is completely polarised. The intensity of light does not change in polarisation.
