Question
Write laws of reflection.
✓

Answer

→(i) The angle of incidence and the angle of reflection are same. (i = r)
(ii) The incident ray, reflected ray and the normal to the reflecting surface at the point of incidence lie in the same plane. This plane is called the plane of incidence.
(iii) The incident ray and reflected ray lie on opposite sides of the normal.
