Question

Which of the following statements is incorrect with regards to plane mirrors?

• A. Image distance is equal to object distance.
• B. Height of image is equal to height of the object.
• C. The plane mirror can only form a virtual image.
• D. The plane mirror forms a virtual image for a real object.

Answer 1

The correct option is C The plane mirror can only form a virtual image.

For a plane mirror,

Image distance = Object distance.

The magnification produced by a plane mirror is equal to $1$.

$\therefore$ Height of image is equal to height of the object.

The plane mirror can form real image of the object as well. If the object is virtual, image formed by a plane mirror is real.

If the object is real, image formed by a plane mirror is virtual.



Hence, option (c) gives the incorrect statement.
