Question

If the boy is standing 1m from the plane mirror, Where will his image seem to be located?

• A. 1m behind the mirror
• B. 2m behind the mirror
• C. 1m in front of the mirror
• D. 2m in front of the mirror

Answer 1

The correct option is A

1m behind the mirror

Step 1: Given data

The boy is standing 1m from the mirror.

Step 2: Analyzing the image formation

1. Assume a boy is standing in front of a plane mirror. When the boy walks toward the mirror, the image of the boy in the plane mirror walks toward the mirror as well.
2. If the boy walks two steps back from the plane mirror, so does the reflection.
3. The boy's distance from the plane mirror and the image's distance from the mirror are the same.
4. Because of the apparent left-to-right inversion, when a boy in front of the plane mirror raises his left hand, the image of the youngster raises his right hand.
5. The plane mirror's image is upright, the image and object are the same sizes, and the image distance from the plane mirror is equal to the object's distance from the mirror.
6. Demonstrating with the help of figure

Thus, if the boy is 1 meter away from the plane mirror, his picture appears to be 1 meter behind the plane mirror.

Hence, option A is the correct answer.
