Reflection of Light: The phenomenon of bouncing back of light rays in the same medium on striking the smooth surface is known as a reflection of light.

Incident Ray: The ray of light that straightaway falls on the reflecting surface from the object or a source is known as an incident ray.

Reflected Ray: The ray of light which is supposed to be reflected after striking the reflecting surface is known as the reflected ray.

The angle of Incidence: The angle that is formed between the incident ray and the general at the point of incidence is known as the angle of incidence, and it is generally represented by ∠i.

The angle of Reflection: The angle that is formed between the reflected ray and the general at the point of incidence is known as the angle of reflection, and it is generally represented by ∠r.

Normal: A straight line perpendicular to the reflecting surface that acts as a separation between the plane of incidence and the plane of reflection is known as the normal.

There are two laws of reflection :

1) Angle of incidence is always equal to the angle of reflection, i.e., ∠i=∠r.

2) The incident ray, the reflected ray, and the normal at the point of incidence, all lie in the same plane.
