Incident ray is defined as:
The ray that hits the reflecting surface
The ray that bounces off the reflecting surface
The ray that is always perpendicular to the reflecting surface
None of the above
The ray that is incident on the reflecting surface is known as the incident ray.
The laws of reflection state that the incident ray, reflected ray and the normal to the surface of mirror lie in different planes.
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.
