Question

When an image of an object is seen in a plane mirror, the distance from the mirror to the image depends on:

• A. the distance of the observer from the mirror
• B. the distance of the object from the mirror
• C. the distance of both the observer and the object to the mirror
• D. the thickness of the mirror

Answer 1

Answer: (B)

the distance of the object from the mirror

For plane mirrors, the image distance is the same as the object distance. The image distance from the mirror does not depend on the distance of the observer from the mirror. Thus if we change the object distance then only the image distance or the distance between the object and image will be affected.
