Incident light ray:                  Reflected light ray:
It’s the light ray that fall on      It’s the light ray that returns
thereflecting surface                back from the reflecting
                                     surface
Angle of incidence:
The angle between the incident       Angle of reflection:
rayand the normal to the
surface                              The angle between the reflected
                                     ray and the normal tothe surface.

If light ray falls perpendicular on the reflecting surface, it will
reflect itself.

Bec.
Angle of incidence = angle of reflection = zero

Mirrors are of two types:            2-Spherical mirrors
   1- Plane mirror
