उत्तर
Given, a distance of boy from the mirror = 3 m
(a). The distance of the image from mirror = distance of boy from the mirror = 3 m
Distance between a boy and his image = distance of boy from the mirror + distance of the image from mirror = 3+3 = 6 m
(b). Now, a distance of boy from the mirror = 4 m
The distance of the image from mirror = 4 m
Distance between a boy and his image = distance of boy from the mirror + distance of the image from mirror = 4+4 = 8 m.
