A device by which the rays proceeding from a luminous or heated object are thrown back or diverted in a given direction. The reflecting surface may be either plane or curved. In practice it is often made spherical or parabolic. The former does not bring the rays to a true focus, but is easily formed, and is consequently generally employed where extreme accuracy is not sought for. A mir ror is a familiar example of a plane reflector. The material should be as smooth and highly polished as po ible. Sheet-tin is frequently used for common purposes, as for door or hall lamps, or those carried by vehicles, while for other purposes a more perfectly reflecting surface is employed, such as speculum metal or silver protected by gla . Silver is the most perfectly reflecting substance known, absorbing but 9 per cent. of the incident rays, while speculum metal absorbs 37 per cent. Gla itself, owing to its property of totally reflecting incident rays at a low angle, is used in certain cases. Reflectors with parabolic surfaces are employed for throwing the light emanating from objects placed in their foci in parallel straight lines to a great distance, and for converging the heat rays from a distant object, as the sun, to a focus, and also, in connection with eye-gla es, in the reflecting-telescope, which is itself often simply denominated a reflector. The term mirror is le comprehensive than that of reflector, being usually only applied to such surfaces as afford definite images and colors, while a reflector may not merely be used for throwing back the rays of light and heat, or of heat only, but also the waves of sound. 2.
