WebIntroduction: The albedo of an object is a measure of how strongly it reflects light from radiant sources such as the sun. Albedo is the percentage of incoming light that is reflected rather than absorbed. It is thought that the earth’s average albedo is around 30%. Energy in the form of visible radiation (light) from the sun warms the earth.
