The image seen in a plane mirror is virtual.

For all positions of the object, a convex mirror produces a virtual, erect, and diminished image.

For all positions of the object, a concave mirror produces a real, inverted, and magnified image.

Convex mirrors are used to get a strong parallel beam of light.

Concave lenses are also called converging lenses.

Lenses that are thinner in the middle than at the edges are called convex lenses.
