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
Answer: (b) 1 m
For a plane mirror, the distance between the object and the mirror will be the same as the distance between the image and the mirror.
Hence, the distance between the object and the image will be twice the distance between the object and the mirror, i.e., 0.5 ×\times× 2 = 1 m.
