Answer:
There are two laws of the reflections, which are:
(1): When a ray of light is reflected from a surface then, the ray of light which incident on the surface ( called incident ray ), the ray of light which reflected from the surface ( called reflected ray ) and the normal to the plane of the mirror, all these lie in the same plane.
(2): The ray of light, when strikes a surface, reflects in such a way that the angle with which it incident ( called angle of incidence ) on the surface with respect to the normal to the surface is always equal to the angle with which the light ray is reflected ( called angle of reflection ) from that surface with respect to the normal to the surface.
