The resulting optical mirror specifically reflects the light of a certain wavelength. Reflectivity of a Bragg mirror depends on the materials, the number of layers applied, and their thicknesses.

Meanwhile, work by Hockney, Falco and other researchers has demonstrated that knowledge of optical techniques, such as the use of curved mirrors and camera obscuras, was known to artists in Europe ...
