The incident and reflected rays follow the laws of reflection at the point of incidence (point P) on the concave mirror, making equal angles with the principal axis. This adherence to the laws of reflection ensures that the angle of incidence and the angle of reflection are equal.
When an oblique ray is incident towards a point P (pole of the mirror) on a concave mirror, what determines the angles of incidence and reflection at the point of incidence?

The angles of incidence and reflection at the point of incidence (P) on a concave mirror are determined by the law of reflection. According to this law, the angle of incidence (the angle between the incident ray and the normal at the point of incidence) is equal to the angle of reflection (the angle between the reflected ray and the same normal). The normal is a line perpendicular to the mirror’s surface at the point of incidence. The law of reflection governs the behavior of light rays, ensuring that the angles of incidence and reflection are equal, contributing to the predictable reflection of oblique rays.
