albedo
[physics] A measure of the reflectivity of an object or surface; the ratio of the amount of radiation reflected by a body to the amount of energy striking it.
Albedos of typical materials in visible light range from up to 90% for fresh snow, to about 4% for charcoal, one of the darkest substances. Deeply shadowed cavities can achieve an effective albedo approaching the zero of a blackbody.
38. Albedo (ratio of reflected light to total amount falling on surface). If greater: Runaway ice age would develop. If less: Runaway green house effect would develop.
Earth Albedo Is the reflectivity of the Earth's atmosphere and surface combined. Measurements indicate that the average Earth albedo is approximately 30%.

It has a very low albedo. Color constancy in the visual system recalibrates the relations between colors of an object and its surroundings; however, there is nothing next to the Moon to reflect the light falling on the Moon, ...
On an opaque surface, there is no radiative transmission through the surface, therefore, with given albedo (a ) or absorptivity ( zetashort), ...
