ABSTRACT
P5.1. Geometric Optics. Radiometry P5.1.1. Geometric Optics ◮ Fundamental laws of geometric optics. Optics studies the electromagnetic radiation of optic (light) range (see Subsection P4.2.2) as well as phenomena arising in its propagation in space and under interaction with matter. Geometric optics does not consider the wave character and polarization of light radiation and deals with notions of light rays pointing out the direction of light propagation and narrow light beams formed by light rays.
