...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. 47. From... | |

...Simple Mirrors.— The chief catoptric properties of mirrors depend upon a single law of light, namely ; that the angle of incidence is always equal to the angle of reflection. To find the direction of a ray of light reflected from any surface, the direction in which... | |
