Incident
ray : - The ray of light which strikes the Plane mirror, or
any other surface is known as incident ray.
Point
of incidence : - It is the point at which the ray of Light hits the Mirror.
Reflected ray – All reflected ray correspond to a particular incident ray. A reflected ray, as it corresponds to a given incident ray, represents the light which is reflected by the surface, as an incident ray falls on it.
Normal
Ray – It is a light ray which is perpendicular to a surface, i.e it hits
the surface at 90 degrees.
Angle of Reflection - The angle formed between the surface, normal and the reflected ray is known as angle of reflection.
Angle of Incidence - The angle between Incident ray and the normal to the surface is known as the angle of incidence.
Laws of reflection – This law states that when a ray of light hits a surface, angle of Incidence is always equal to angle of reflection. Further all of the following, namely, an incident ray, Reflected ray and Normal ray, all lie on the same Plane.
