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:
(a) Both A and R are true, and R is correct explanation of the assertion.
(b) Both A and R are true, but R is not the correct explanation of the assertion.
(c) A is true, but R is false.
(d) A is false, but R is true.
Assertion: Keeping a point object fixed, if a plane mirror is moved, the image will also move.
Reason: In case of a plane mirror, distance of object and its image is equal from any point on the mirror.
(a) Both A and R are true, and R is correct explanation of the assertion.
Explanation:
The image formed in a plane mirror is at the same distance behind the mirror as the object is in the front of the mirror. Image and the object are at equal distances from a plane mirror.
