 |
| Reflection of a light ray from a
plane mirror
|
- The incidenct ray, the reflected ray, and the normal to the reflecting interface at the point of incidence all lie in the same plane.
- The angle of incidence equals the angle of reflection.
Normal: a line at 90° to the surface of a mirror
Incident ray: A ray of light going to the mirror
Reflected ray: A ray that comes off the mirror
Angle of incidence: The angle between the incident ray and the normal
Angle of reflection: The angle between the reflected ray and the normal
