Objectives of the course
It is a basic course of 7.5 credits consisting in 56 hours of lessons and in 28 hours of exercises. The course has a double objective. On one hand it provides an unitary and systematic description of the electromagnetic and wave phenomenology and on the other hand it emphasises the methodology of scientific investigation for the treated physical phenomena. The subjects treated in the course are divided in four sections. Finally in a last fifth section some basic concepts of modern physics with some specific technological applications are considered.

Expected skills
Ad the end of the course the student will acquire the competences which will permit him to tackle, critically, specific problems emerging during the study of electromagnetic and wave phenomenology. Finally the student will be able to treat some elementary problems of modern physics.

Prerequisites
In order to better understand the subjects treated in the present course it is required a familiarity, previously acquired, with the contents of the courses of Physics I, Analysis I, and Geometry.
