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
$(a)$. 2 m
$(b)$. 1 m
$(c)$. 0.5 m
$(d)$. 0.25 m
The distance between the object and the image formed will be equal to the sum of the distance between the object and mirror and the distance between mirror and image.
So, the distance between object and image$=$Distance between object and mirror$+$distance between mirror and image$=(0.5+0.5)\ m=1\ m$
So, option $(b)$ is correct.
