The course aims to provide the fundamental notions of wave phenomena, physical optics and geometric optics, in the field of classical physics.
The course consists of lectures on theory and exercises.
KNOWLEDGE AND UNDERSTANDING:
Students must acquire knowledge of the part of classical physics concerning waves and optics.
APPLYING KNOWLEDGE AND UNDERSTANDING:
The student must be able to solve simple problems in an autonomous way and to expose and demonstrate the different topics covered during the lessons.
Students must be able to apply their knowledge and understanding in order to analyze and conceptualize the proposed physical problems. They must also have adequate skills to devise and support arguments on the proposed topics.
Finally they must be able to identify the essential elements of a simple physical problem and know how to model them, making the necessary approximations.
Students must be able to critically analyze the topics covered and possibly make autonomous bibliographic research to deepen the proposed themes.
They must be able to present the topics covered with depth and language properties, analyzing their various aspects and connections.
To stimulate and direct students to the consultation of several manuals, in order to learn the same topic from more than one source, thus deepening their understanding and at the same time extending their analytical skills.
