...is a scientific mode of expressing the direction in which the reflection will take place, by saying that the " angle of incidence is always equal to the angle of reflection," which in familiar language means, that however slanting the ball may approach the wall, it will rebound... | |

...the angle of reflexion ; and as the angle AOC is equal to the angle GFC, we deduce the general law, that the angle of incidence is always equal to the angle of reflexion; a law applying not only to the movement of ponderable but of imponderable matter, as light.... | |

...reflection ;t the more oblique is the line of incidence, the more so will be the line of reflection. The angle of incidence is always equal to the angle of reflection ; thus the angle abd, is equal to the angle abc, because the line, ab, divides the larger angle, c... | |

...rebound with equal velocities. In cases where elastic bodies strike on a hard surface, in the rebound, the angle of incidence is always equal to the angle of reflection. Thus, let d, Fig. 46, strike on the surface c, the angle dcb is equal to bc a. The same law holds in... | |

The disciples of Plato contributed not a little to the advancement of optics, by the important discovery they made, that light emits itself in straight lines, and that the angle of incidence is always equal to the angle of reflection. Plato terms colours...
