Surface of a Normal mirror is flat. If that surface is made to bulge then it becomes a spherical mirror. When such a mirror is silvered from the bulged side and viewed from where it has bulged inward then that mirror is called a Concave Mirror. The image in a concave mirror will appear enlarged when kept close and small and inverted when kept at a distant as its centre of curvature lies in front of the mirror. It is also called a converging mirror.
