Solution

## The correct option is A Both the statements are correct and Statement II infers from Statement IAn image formed by the real intersection of the rays after being altered by an optical device is a real image. In this case we can say that the image formed by real intersection of the rays after getting reflected from the mirror is a real image. So, to form a real image, the rays after getting reflected from the mirror, must intersect. In a convex mirror, the rays from a point source after reflection diverge (Can be seen in the diagram)( convex mirror is a diverging mirror) and hence can never meet or intersect . So, a convex mirror can never form a real image for a point source of light. So we see that not only both the statements are correct but also, the second statement infers from the first. Although, there is a case possible when a convex mirror can form a real image. See the diagram below : While, this is not the case of a point source of light as we can see, the incident rays are converging whereas a point source of light would always produce diverging incident rays. This is the condition with a virtualObject, which you will learn about soon, in an upcoming module.
