If an object is placed at a distance of 0.5 m in front of a plane mirror

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

  1. 2 m
  2. 1 m
  3. 0.5 m
  4. 0.25 m

Answer

The image formed by a plane mirror is at the same distance behind the mirror as the object is in front of it.

Therefore, the distance between object and image is given by distance between object and mirror + distance between mirror and image

= 0.5 m + 0.5 m

= 1 m

The correct option is B.
