Concave and convex mirrors are the types of spherical mirrors.

Concave mirrors have an inward curvature in the centre and reflect light inward to focus it on a single focal point. Concave mirrors provide a variety of images depending on the distance between the mirror and the item.

Convex mirrors have an outward bulge in the center that allows light to fall directly on the item. It's also known as a diverging mirror since it can diverge the rays that fall on its surface after reflection. This is a reference to the fact that parallel rays diverge when they touch the reflected surface of a convex mirror.
