Methodological support
The set has methodical instructions in Russian for performing 31 experiments. The description of the experiments is accompanied by photographs showing what results the teacher can obtain during the demonstration.
Software for conducting computational modeling
The software contains a calculation model that provides calculation of refraction of light rays on the lens surfaces in order to determine the focal length of the lens with specified values of the surface curvature radii. The on-screen interface of the software provides input of values of the lens surface curvature radii and the nature of these surfaces (concave, convex, flat), the radius of the light beam, and the refractive index of the lens material.
The calculation model has an electronic methodological manual describing numerical experiments that can be performed using this model.
