Dielectric Mirrors Are Made to Have Extremely High Reflectance

Multiple Choice

A) by stacking thin layers of a single dielectric material on a glass backing so that the reflections from the surfaces of the layers undergoconstructive interference.
B) by stacking thin layers of a single dielectric material on a glass backing so that the reflections from the surfaces of the layers undergo destructive interference.
C) by stacking thin layers of different dielectric materials on a glass backing so that the reflections from the surfaces of the layers undergo constructive interference.
D) by stacking thin layers of different dielectric materials on a glass backing so that the reflections from the surfaces of the layers undergo destructive interference.
