Which statement best expresses the law of reflection for a light ray incident on a smooth plane surface?
(a) The angle between the incident ray and the surface equals the angle between the reflected ray and the surface.
(b) The angle of incidence plus the angle of reflection is 90∘ for a smooth surface.
(c) The angle between the incident ray and the normal equals the angle between the reflected ray and the normal.
(d) The angle of incidence is twice the angle of reflection for any smooth surface.
