Law of Reflection
Angle of reflection = Angle of incidence.
The correct trajectory of the incident ray.
The ray which is entering the surface.
The ray which is reflected or bounced of the surface.
Angle of Incidence
The angle at which the incident ray is entering the surface.
Angle of Reflection
The angle at which the reflected ray is bounced off, and is equal to the angle of incidence.
13. Plane mirror: a surface capable of reflecting a ray.
