Question

If half of a plane mirror's reflective surface is covered with a dense black paper, then which of the following statements are true?

• A. Image has a different shape when compared to the object.
• B. Size of the image is same as that of the object.
• C. Distance of image formed and object placed from the mirror is equal.
• D. Image appears brighter than the object.

Answer 1

Answer: (B), (C)

The correct options are
B Size of the image is same as that of the object.
C Distance of image formed and object placed from the mirror is equal.

If we cover a part of plane mirror then its field of vision would reduce i.e. the mirror becomes smaller in size. There will be no effect on the shape, size and nature of the image that it forms.
