Demonstration set on geometrical optics

The set is intended for studying the laws of geometrical optics and demonstrating the work of some optical devices. The set of equipment allows performing at least 32 experiments devoted to such phenomena as rectilinear propagation of light; shadow and penumbra formation; specular reflection of light; diffuse reflection of light; dependence of the focal length of the lens on the refractive index of the external medium; connection of the distance from the object to the lens with the distance from the lens to its reflection; spherical aberration; chromatic aberration; action of the optical system of the eye; passage of light through a plane-parallel plate.
