what is albedo
Asked by | 10th May, 2008, 08:04: PM
The albedo of an object is the extent to which it diffusely reflects light from the sun.
If an object has a high value of albedo then it will look bright, if albedo has a small value it will look dull.
The albedo of an object will determine its visual brightness when viewed with reflected light. For example, the planets are viewed by reflected sunlight and their brightness depends upon the amount of light received from the sun and their albedo. Mercury receives the maximum amount of sunlight, but its albedo is only 0.1 so it is not as bright as Venus, that has a higher albedo.
