Two simple models of the spatial dependence λ(z) are used with first- and secondorder perturbation theory (developed in [1]) to determine the intensity of the emerging radiation and the coefficient of reflection in the case of monochromatic scattering in a semiinfinite medium. Higher-order perturbation theory is briefly discussed. The results obtained can be used in model calculations to take into account the roughness of the surface of a light-scattering medium, and to determine the light-scattering characteristics of diffusely reflecting dyes as functions of surface properties.
