The point where a ray of light strikes the surface of a
mirrors is called the point of incidence.
If a normal is drawn to the surface at this point, the
angle4 which the incident ray makes with it is called the
angle of incidence.
The angle which the reflected ray makes with the normal is
called the angle of reflection.
The plane containing normal and incident ray is called the
plane of incidence and the plane containing normal and
reflected ray is called the pane of reflection.
Law of Reflection :- They are
1. The incident ray, the reflected ray and the normal to be
surface at the point of incidence. All lie in the same plane.
2. the angle of incidence is equal to the angle of reflection.
