Answer:
the convex mirrors have the property to diverge light rays. this is because light rays diverge from the surface of a convex mirror. the divergent ray appears to come behind the surface of the mirror. Since the image is formed behind the mirror they cannot be received on a screen so the image is not real.
Explanation:
Convex mirrors reflect light outwards (diverging light rays) and therefore they are not used to focus light. The image is virtual, erect and smaller in size than the object, but gets larger (maximum up to the size of the object) as the object comes towards the mirror.
