WebSep 7, 2024 · Metallic Reflection. When a light beam encounters a material, radiation can be absorbed or reflected by the surface. Metals are known for having high reflectivity, which explains their shiny appearance. Since the reflectance of light by metals is high their absorption is low because the sum of both must correspond to 100% of the incident light. Webmaterial present in a sample as well as the wavelength of the radiation employed. In this experiment the absorption of light of 522 nm wavelength by a sample solution will lead to an analysis for a trace amount of iron in an unknown sample.
