Reflectivity of gold
WebJul 20, 2001 · Gold’s reflectivity of ultraviolet and visual light rays is low, however, it has high reflectivity of infrared and red wavelengths. Gold is a good conductor of heat and electricity, and is unaffected by air, nitric, hydrochloric, or sulphuric acid and most other reagents. A mixture of one part nitric acid with three parts hydrochloric acid ... WebNov 22, 2013 · The reflectivity of homogeneous binary gold alloys of formula Au x M 1-x, where M is silver, platinum, and palladium, has been modelled using only the available optical constants of the pure parent metals, gold, silver, platinum, and palladium. The estimated reflectivity curves are compared with experimentally determined reflectivity …
