A ray of light incident on any spherical mirror follows laws of reflection.
(i) In case of a concave mirror, the line joining the point of incidence ray and the center of curvature forms the normal as shown. The reflected ray goes on the other side of the normal following laws of reflection.

(ii) In the case of a convex mirror, the normal at the point of incidence is as shown. The reflected ray goes on the other side of the normal. Following laws of reflection as shown. Hence, it goes away from the principal axis.
