The image distance for a plane mirror.
Answer to Problem 1RQ
The image distance for a plane mirror is equals the object distance.
Explanation of Solution
The ray incident along normally to the mirror gets reflected directly back along the normal. So it appears to have originated behind the mirror on the normal. The light ray that strikes the mirror at an angle
The two projected paths cross behind the mirror at point
Conclusion:
Therefore, the image distance for a plane mirror is equals the object distance.
