Abstract
Aim. The purpose is to reveal the features of the interaction of visible light with transparent inhomogeneities (droplets) in the atmosphere under isothermal conditions.
Methodology. The intensity of the incident radiation is limited by the intensity of daylight. In this case, the interaction of radiation with a drop is limited by elastic scattering (Rayleigh scattering). Two limiting cases of the interaction of light with a drop are considered: the approximation of ray (geometric) optics and wave optics in the Rayleigh scattering approximation. This makes it possible to study the effect of droplet sizes on light scattering depending on the wavelength.
Results. The dependence of scattering on the size of the droplet and on the entrance of radiation into the droplet is investigated within the limits of the beam optics and the accepted intensity. In the framework of Rayleigh scattering, the known dependences of the scattering intensity on the wavelength of light and the radius of the drop are realized.
Research implications. Within the accepted conditions of interaction of light with a (transparent) drop of water, the models considered (the ray optics approximation and the Rayleigh scattering approximation) revealed the dependence of scattered light on the size and shape of droplets, and also confirmed the characteristic dependences of the scattering intensity on the wavelength of light and the radius of the drop.
