Question

If the boy is standing 1m from the mirror, where will his image seem to be located?
A) 2m behind the mirror.
B) 1m behind the mirror.
C) 2m in front of the mirror.
D) 1m in front of the mirror.

Answer 1

Hint: When we put an object in front of a plane mirror, the image of the objects moves accordingly as the object moves on the other side of the mirror. If the object moves in front of the mirror, the image also moves towards the mirror.

Complete step by step answer:

Let us suppose a boy is standing in front of a mirror. We will notice when the boy moves toward the mirror, the image of the boy in the mirror is also walking towards the mirror, and if the boy takes two steps back from the mirror, then the image also does the same. The distance of the boy from the mirror and the distance of the image from the mirror is equal.
The image formed by the mirror is erect, the size of the image and object is the same, and the image distance from the mirror is the same as the object distance from the mirror.

So if the boy is standing 1m from the mirror, then his image seems to be located 1m behind the mirror. Therefore Option D is the correct answer.

Note:
 When a boy in front of the mirror raises his left hand, then the image of the boy raises his right hand, this happens because of the apparent left to right reversal. This left-right reversal is called lateral inversion. Lateral means sideway, and inversion means reversal. The lateral inversion property of the plane mirror is used by ambulance vans. If the question said what is the distance between object and image formed then it will be 2m.
