Q. The incident ray, reflected ray and the normal in case of a plane mirror are in the ..............

Q. Laws of reflection are applicable even if the incident ray and the reflected ray are in same plane and the normal is in a different plane:

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.

The laws of reflection state that the incident ray, reflected ray and the normal to the surface of mirror lie in different planes.
