Information About

Albedo




The albedo of an object is the extent to which it reflects light, defined as
the ratio of Reflected to Incident Electromagnetic Radiation . It is a Unitless measure indicative of a surface's or body's diffuse Reflectivity . The word is derived from ''albus'', a Latin word for "white".

The albedo is an important concept in . In general, the albedo depends on the Direction and directional distribution of incoming radiation. Exceptions are Lambertian surfaces, which scatter radiation equally in all directions, so their albedo does not depend on the incoming distribution. In realistic cases, a Bidirectional Reflectance Distribution Function (BRDF) is required to characterise the scattering properties of a surface accurately, although albedos are a very useful first approximation.
