Reflection
The incident ray, the reflected ray and the normal to the
reflection surface at the point of the incidence lie in the
same plane.
The angle which the incident ray makes with the normal is
equal to the angle which the reflected ray makes to the
same normal.
The reflected ray and the incident ray are on the opposite
sides of the normal.
