This paper presents the content and structure of learning activities aimed at the study of Babinet’s principle by undergraduate students and its use in the experimental justification of Rayleigh criterion to resolve the power of an optical device. The learning activities include the elementary theory of Fraunhofer diffraction at a slit, wire, and circular aperture and training experiments confirming the results of the theory. This content is structured in the form of two sets of theoretical and experimental tasks that are to be performed by the students independently. Possible variants for solving the problems in the tasks are also considered.
