General mathematical expressions serving as analytical approximations for the far-field amplitude in high-frequency scattering of electromagnetic waves on a dielectric sphere. The approximations can be used to solve problems of radiative transfer in the visible and infrared spectrum in such media as natural fog and clouds, as well as in dense planetary atmospheres, especially if the scatterers vary greatly in size.
