👉 Translucencies are a type of optical phenomenon that occurs when light is dispersed or refracted in a medium. When light passes through a material, it may be scattered, refracted, or reflected by the surface of the material. The degree to which light is scattered or refracted can depend on the angle and direction of travel, as well as other factors such as temperature, humidity, and density. For example, in a vacuum, light is completely transparent and does not scatter or reflect.
