The first two matrix elements for light scattering by water droplets with radii of 10, 100 and 500mm and by polydesperse systems of spherical particles in a wide range of wavelengths in the visible were calculated using the Mie-theory relations. The scattering phase functions for different frequencies in the region of glory for the 170-180°angles are presented. It is shown that the specific behaviour of the degree of polarization in the region of glory cannot be interpreted within the framework of the interference effect or surface waves. The angular position of the glory and the degree of polarization arc found as a function of mode and variance of the particle distribution within clouds.
