The incident ray is reflected obliquely, following the laws of reflection at the point of incidence, making equal angles with the principal axis.
What happens when a ray of light is incident obliquely towards a point P (pole of the mirror) on a concave mirror?

When a ray of light is incident obliquely towards a point P (pole) on a concave mirror, it reflects according to the law of reflection. If the incident ray is directed through the pole towards the mirror’s center of curvature, it reflects back along the same path. If the incident ray is directed parallel to the principal axis towards the pole, it reflects and passes through the focal point. This behavior demonstrates the converging nature of concave mirrors, focusing parallel rays or rays directed towards the center of curvature to specific points, contributing to their application in imaging systems and optical devices.
