Reflection of Light
Reflection of Light: Overview
This topic discusses reflection, where a ray of light falls on a surface and gets reflected. As per its law, the incident ray, the reflected ray and the normal lie in the same plane and the angle of incidence is equal to the angle of reflection.

A point object can be considered as the source of light.
Extended objects can be considered as the group of point objects in a ray diagram.
A ray of light is incident on a plane mirror and the angle of reflection is . Calculate the angle between the incident ray and the reflected ray.
