Objectives

The course objective is to consolidate some of the objectives introduced in the “Fisica Generale 1” course, giving the concepts, the physical quantities and methods of the Physics of Electromagnetism in presence of electrical and magnetic fields variable in time. The oscillatory phenomena will be reviewed and the wave propagation will be introduced. In the second part of the course the Optical Physics will be introduced: reflection, interference and diffraction phenomena will be discussed. The physical concepts and laws will be applied in the resolution of simple problems and in the laboratory experiences. Whenever possible the connections with the research in Fundamental and applied Physics will be discussed, in order to let the students understand the deep connection between science and technology. In the last part of the course, depending on the time available, a brief introduction to the concepts of modern Physics will be given, particularly related to the items of interest for Electronic Engineering.
