Reflection:- The process of sending back light rays which falls on the surface of an object is called reflection of light.

According to Law of Reflection,

1).Θi=Θr

Where,

Θi = angle of incidence.

Θr = measurement between the ray and a line normal to the surface that intersects the surface at the same point as the ray.

2).When reflection of light occurs, the incident ray, reflected ray and normal to the reflecting surface at the point of incidence of the light ray, lie in the same plane.
