WebThe amount of energy reflected by a surface is called albedo. Dark colors have an albedo close to zero, meaning little or no energy is reflected. Pale colors have an albedo close … WebAlbedo is the proportion of incident light that is reflected away from a surface.. Diffuse reflection is the reflection of light in many directions, rather than in just one direction like a mirror (specular reflection).. In the case of ideal diffuse reflection (Lambertian reflectance), incident light is reflected in all directions independently of the angle at which it arrived.

"WebAlbedo can either be expressed in a ratio (dimensionless number) or as a percentage. The higher the value, the more energy is reflected back to the source. Complete reflection is 1 or 100%, and complete absorption is 0. Surfaces that have a low albedo such as rocks or water are dark colored and will absorb more incoming solar radiation.
