Question

An object of height 10 cm is placed in front of a convex mirror. Which of the following can be the possible height of its image?

• A. 10 cm
• B. 12 cm
• C. 8 cm
• D. - 8 cm

Answer 1

The correct option is C 8 cm

The image formed in a convex mirror is always virtual, erect and diminished whatever be the position of the object.
Hence, the size of image will be less than 10 cm.
Also, according to the sign-convention, the height above the principal axis is taken as positive.
So, the correct answer is +8 cm.
