Question

Assertion (A): A convex mirror always forms an image behind it and the image formed is virtual. 

Reason (R): According to the sign convention, the focal length of a convex mirror is positive.

Answer these questions by selecting the appropriate option given below:

A. Both A and R are true, and R is the correct explanation of A.

B. Both A and R are true, and R is not the correct explanation of A.

C. A is true but R is false.

D. A is false but R is true

Answer 1

Correct option is (B) Both A and R are true, and R is not the correct explanation of A.

The virtual image formation is due to the reflection of diverging rays, not because of the sign of the focal length.
