WebA 100-nm layer of aluminum or silver makes an excellent reflector for the visible spectrum. Aluminum reflects about 90 percent of the light across the visible spectrum, while silver reflects about 95 percent. The reflectance of a metal mirror can be calculated from the index of refraction n and the extinction coefficient k of the metal. The ... WebThe first big reflectors were built by William Herschel (1738-1822). During the course of his career, Herschel constructed more than four hundred telescopes. The largest of these reflectors was the 40 ft (12 m focal length) telescope. This telescope with a primary mirror
