The reflection in which parallel incident rays emrge non parallel from a surface is called as

Suppose you have a plane mirror that reflects light. When light strikes the mirror, the light is reflected off the surface. The law of reflection says that:

Statement 1: The angle of incidence (incoming ray) is equal to the angle of reflection (outgoing ray).

Statement 2: The angle is measured from a perpendicular line to the surface called as Normal.

Statement 3: Incident ray, reflected ray and the normal does not lie in the same plane.

Statement 4: The law works for the plane as well as for curved surfaces.
