"WebAlbedo is a non-dimensional, unitless quantity that indicates how well a surface reflects solar energy. Albedo varies between 0 and 1. Albedo commonly refers to the "whiteness" of a surface, with 0 meaning black and 1 meaning white. A value of 0 means the surface is a "perfect absorber" that absorbs all incoming energy.

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. Webthe angle of reflection is 90° if the angle of incidence is 90° In the second example, if a light ray travelling along the normal hits a mirror, it is reflected straight back the way it came.

Gloss is an optical property which indicates how well a surface reflects light in a specular (mirror-like) direction. It is one of the important parameters that are used to describe the visual appearance of an object. The factors that affect gloss are the refractive index of the material, the angle of incident light and the surface topography.
