Albedo: Ratio of reflected radiation to incident radiation
The albedo of an object is the extent to which it reflects light, more specifically light which comes from the Sun.
It is 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".
