Question 3
If an object is placed at a distance of 0.5 m in front of a plane mirror, the distance between the object and the image formed by the mirror will be
(a) 2m
(b) 1m
(c) 0.5m
(d) 0.25m
The distance between object and mirror will be same as the distance between image and mirror. Hence, the distance between object and image will be 0.5 × 2 = 1 m.
