Which has a lower albedo, a black sheet of paper or a white sheet of paper?

Well let's see, the substance with the highest albedo value will absorb less light and will reflect most of the light falling on it. The substance having the lowest albedo will absorb most of the lights falling on it. A black sheet of paper will absorb most of the light falling on it, so this means that a black sheet of paper will have the lower albedo

yes it would be pssible
