Detailed Solution

Concave lenses and convex mirrors always diverge light rays.
The concave lens and the convex mirrors diverge the light rays because of the structure of their curved part and are hence called the diverging lens and mirrors, respectively. On the other hand, the concave mirror and convex lens each converge all the rays parallel to the principal axis towards their respective principal focus. Thus, a convex lens is termed a converging lens, and a concave mirror is termed a converging mirror.
