The albedo, (Latin for white) is a measure of reflected sunlight. Charcoal has an albedo of 0,04; snow 0,9 The planet with the highest albedo is Venus, whereas Mercury is theâ¦ lowest.
Because albedo is the ratio of all reflected radiation to incident radiation, it will include both the diffuse and specular radiation reflected from an object. It is, however, common to assume a surface reflects in either a totally specular manner or a totally diffuse manner, as this can simplify calculations.
