What is meant by the reflection of light ? Define the following terms used in the study of reflection of light by drawing a labelled diagram (a) Incident ray (b) Point of Incidence (c) Normal (d) Reflected ray (e) Angle of incidence (f) Angle of reflection

The ray of light which incident on a surface is called incident ray.
The point in which the incident ray strike in the surface is called the point of incidence.
The perpendicular drawn onto the surface of the point where the ray incident.
The ray of light which sent back from the reflecting surface is called reflected ray.
The angle which is made by the incident ray and the normal which is drwan through the point of incidence is called angle of incidence
The angle which is made by the reflected ray and the normal which is drwan through the point of incidence is called angle of reflection.

Final answer:

The ray of light which incident on a surface is called incident ray.
The point in which the incident ray strike in the surface is called the point of incidence.
The perpendicular drawn onto the surface of the point where the ray incident.
The ray of light which sent back from the reflecting surface is called reflected ray.
The angle which is made by the incident ray and the normal which is drwan through the point of incidence is called angle of incidence.The angle which is made by the reflected ray and the normal which is drwan through the point of incidence is called angle of reflection.
