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: The size of the mirror affect the nature of the image.
Reason: Small mirrors always form virtual images.
✓

Answer

  1. A is false, but R is true.

Explanation:

The size of the image does not affect the nature of the image, except that a bigger image as it gathers more tight rays due to wider aperture.
