According to the Minnaert model of surface scattering, the BRDF R is given by

where A and a are constants; θ₀ and θ₁ are the angles between the incident and scattered rays, respectively, and the surface normal; and the BRDF has no azimuthal dependence. Show that the reflectivity r at angle θ₀, and the diffuse albedo r_d, are related through

in this model.
