Question

Which has the lowest albedo?
A) dark surfaces
B) light surfaces
C) Both A & B
D) None of the above

Answer 1

None of the above because black soil has the lowest albedo

hope its helpfull

Answer 2

Answer: The corrcet option is  A) dark surfaces

Explanation:

Albedo is a measure of reflectivity. It is dimensionless. It is generally measured on a scale from 0 (corresponding to a specific black body which absorbs all incident radiation) to 1 (corresponding to a specific body which reflects all incident radiation).

A low albedo refers to a surface which reflects a small amount of the incoming radiation and absorbs the rest of the radiation. This clearly indicates that all black surfaces have the lowest albedo.

Fresh snow reflects approximately 95 percent of the sun's rays so it has the highest albedo.

Hope it helps!
