Assertion : By roughening the surface of a glass sheet its transparency can be reduced. Reason : Glass sheet with rough surface absorbs more light.

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

C. If assertion is true but reason is false

Step-by-step solution

When glass surface is made rough then the light falling on it is scattered in different direction due to which its transparency decreases.
