Which of the following statements is/are not correct about image formed by a plane mirror?
I. The magnification produced is 1
II. The image distance is same as the object distance
III. The image is real
IV. The image is laterally inverted
Answer Details
The correct option is III only.
When an object is placed in front of a plane mirror, the image formed is virtual, upright, and laterally inverted. The virtual image means that the light rays don't actually converge at the position of the image. Instead, they appear to diverge from the image as if they are coming from behind the mirror.
The magnification produced by a plane mirror is always 1, which means the size of the image is equal to the size of the object. The image distance is equal to the object distance, which means the distance between the mirror and the object is the same as the distance between the mirror and the image. Finally, the image formed by a plane mirror is laterally inverted, which means that the left and right sides of the object appear reversed in the image.
Therefore, option III is incorrect because the image formed by a plane mirror is virtual, not real.
