...A perpendicular line drawn to the reflecting surface is called a normal, and the angle contained by the incident ray and the normal is the angle of incidence. The angle of incidence is always equal to the angle of reflection. A mirror may be plane, as an ordinary lookingglass,... | |

...drawn to the surface at the point of incidence, it is said to be normal to the surface at that point. The angle between the incident ray and the normal is the angle of incidence; the angle between the normal and the reflected ray is the angle of reflection. The plane of the incident ray and the normal... | |
