Albedo is the "whiteness" of a surface. It is a reflection coefficient, and has a value of less than one. The albedo of a surface is the ratio of radiation reflected from the surface to the incident radiation. Hope this helps. Have a nice day. Feel free to ask more questions.

I'm trying my best !!!!
