The law of reflection is the angle of incidence is equal to the angle of reflection.
According to the law of reflection, when light strikes a plane surface, it is reflected in such a way that the incident ray, the reflected ray, and the normal ray all fall in the plane of incidence and the angle of reflection is equal to the angle of incidence.
The angle of incidence is the angle at which light enters a surface. The angle between the incoming ray of light and the normal vector of the surface, it is coming into contact with, is known as the angle of incidence. The normal vector is a perpendicular vector originating from an object's plain or surface.
Hence, the law of reflection is the angle of incidence is equal to the angle of reflection.
