Question

An object placed 3 m from a plane mirror is shifted by 0.4 m away from the mirror. What is the new distance between the object and its image?​

Answer 1

Answer:

5 meter

Explanation:

After shifting object 0.5m away from mirror, the distance between the object and the mirror = 2.5 m.

Hence, distance between object and image is 2x2.5 m = 5 m.
