Answer:
In the case of a plane mirror, the distance between the object and the mirror (d1) is same as the distance between image and mirror (d2).
Distance between the mirror and boy image, d2 = 4 m
Therefore, d1 = d2 = 4 m
If boy moves 1 m towards the mirror, then d1 = 4 − 1 = 3m Again, d1 = d2 = 3 m Therefore, the distance between boy and his image is d1 + d2 = 3 + 3 = 6 m
