The 10 ECTs Course is proposed to students of Physical Engineering, of Electronic and Communication Engineering and of Computer Engineering. Aim of the course (1st semester, 2nd year) is to provide the theoretical concepts to be used in all courses of the following semesters. This is therefore a pivotal course for the ensuing career. The course is divided in two sections: - 1st part (6 ECTs-Electromagnetism and Optics), in which fundamental subjects of basic physics are treated, such as: electromagnetism and the Maxwell's equations, electromagnetic waves properties, physical optics, interference and diffraction. THIS PART IS for PHYSICAL ENGINEERING, for ELECTRIC and COMMUNICATION ENGINEERING and for COMPUTER ENGINEERING STUDENTS. - 2nd part (4 ECTs-Introduction to Modern Physics), in which the subjects involve: the crisis of classical mechanics, the transition to the fundaments of modern physics, with emphasis on quantum physics and its implications in terms of methods and practice. THIS PART IS ONLY for PHYSICAL ENGINEERING STUDENTS.

Class exercises concern with simple problem solving activities, in strict correlation with the previous theoretical lectures. In some cases scientific calculators (students' personal property) may be required.
The course is divided in theoretical lessons and exercises with simple problem solving activities, in strict correlation with the previous theoretical lectures. In some cases scientific calculators (students' personal property) may be required. Slides videos and other interactive materials will be used. Exercises to be solved at home (both individually and in groups) will be proposed. All the didactic material will be available on the didactic portal.
