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. colorado state university masters programs https://lonestarimpressions.com
