Consider the following statements and select the correct answer using the code given below: 1. Albedo is the reflective quality of a surface. 2. Albedo is a function of surface colour, angle of incidence and surface texture. 3. Lower angles produce a greater reflection than do higher angle. Smooth surfaces increase albedo, whereas rougher surface reduce it.
