Prerequisites:

General Physics 1, Mathematical Analysis 1, Mathematical Analysis 2, Geometry 
Target skills and knowledge:

This course deals with electromagnetic phenomena, from their experimental observation to their description in terms of general laws. The student will get a knowledge of the experimental tools useful for the study of electric and magnetic phenomena, both static and dynamic, and of the theory which allows their mathematical description, up to Maxwell's equations both in vacuum and in materials. Among the electromagnetic phenomena studied in this course are those related to optics, therefore waves and oscillations will be analyzed thoroughly. 
Examination methods:

Both written and oral, in the same session. A positive evaluation of the written exam is necessary to be admitted to the oral one.
The written exam for admission to the oral exam in the winter session (at the end of the semester), may be substituted by partial written exams (Compitini) during the semester. 
Assessment criteria:

The written exam requires the solution of some simple problems on subjects studied in class.
In the oral exam, the student must show his/her understanding of the phenomenology of electromagnetic events and of the underlying physical laws.
