Small surface spatial wavelengths d scatter the light into large angles θs with respect to the specular direction θspec (= θi), and large spatial wave-lengths of the surface scatter light into angles very close to the specular direction. Equations (12.3) and (12.7) have been used a great deal by opticists (Elson and Websurface wave contributions. Subsequently, we present in Section 3 a comprehensive comparison of the single-scattering properties (extinction efﬁciency, single-scatter-ing albedo, and asymmetry factor) determined from the present geometric-optics surface-wave theory and the exact Lorenz–Mie results and discuss deviations between the two. tsc mink sheets
