उत्तर
David is observing his image in a plane mirror. The distance between the mirror and his image is 4 m. If he moves 1 m towards the mirror, then the distance between David and his image will be 6 m.
Explanation:
If David moves 1 m towards the mirror, then the distance between his image and mirror = 4 - 1 = 3m
So, the distance between David and the mirror = 3
Hence, distance between David and his image = 3 + 3 = 6m
