a boy is standing at a distance of 4m in front of a mirror. he moves 2m towards the mirror in whuch direction will the image move -towards the mirror or away from it
Answers
The image will move towards the mirror.
Explanation:
The boy is at a distance of 4 m away form the mirror.
When he moves 2 m towards the mirror, then the final distance between
the boy and mirror = 4 m-2 m = 2 m.
As we know the separation between the object and mirror is same as the separation between image and mirror, so when boy is at distance of 4 m away form the mirror then image is also at 4 m away from the mirror.
Since boy moves 2 m towards the mirror, therefore image also moves towards the mirror.
Thus, the image will move towards the mirror.

The image will move towards the mirror.
Explanation:
We use plane mirror to see our image. Light rays that fall on the planar surface of the mirror, have the same angle of reflection and angle of incidence. The image is virtual, upright and of the same size as the object.
The boy is at a distance of 4m away from the mirror. We know that the distance of the image is the same as the distance of the object from a plane mirror. So when the boy stands at 4m, the image is also 4m away from the mirror. Same is the case when the boy move moves 2m closer.
Since boy moves 2m towards the mirror, it implies that the image will also move 2m towards the mirror.
