Question

Albedo effect would be relatively higher in

(a) early morning and late evening (b) early morning only (c) noon (d) late evening only

Answer 1

(a) Albedo also varies according to the angle of incidence of the Sun Raysbeing higher for slating rays and lower for vertical or nearly vertical rays. From this we can derive that albedo will be relatively higher during early morning and late evening because at both times, Sun rays are slanting.
