The relationship between the incident ray, the reflected ray, and the normal for a curved mirror depends on the shape of the mirror. In general, the angle of incidence equals the angle of reflection for each point on the mirror surface, and the normal to the mirror at that point bisects the angle between the incident and reflected rays. However, for a curved mirror, the normal is not always perpendicular to the mirror surface, and the focal point and focal length of the mirror also affect the relationship between the incident and reflected rays.
