Question
For two statements are given-one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer to these questions from the codes (a), (b), (c) and (d) as given below:

  1. Both A and R are true, and R is correct explanation of the assertion.
  2. Both A and R are true, but R is not the correct explanation of the assertion.
  3. A is true, but R is false.
  4. A is false, but R is true.

Assertion: ln diffused reflection, a parallel beam of incident light is reflected in different direction.

Reason : The diffused reflection of light is due to the failure of the laws of reflection.

✓

Answer

  1. A is true, but R is false.

Explanation:

Diffuse reflection is caused by the roughness (or irregularities) in the reflecting surface of an object. The laws of reflection are valid at each point even on the rough surface of an object.
