Objectives
THE COURSE FOLLOWS THE ONE CONCERNING THE PHYSICAL CONCEPTS OF CLASSICAL MECHANICS AND GEOMETRIC OPTICS, AND IS SUITABLY ORGANIZED IN ORDER TO GIVE TO THE STUDENTS THE BASIC KNOWLEDGE OF THE FUNDAMENTAL PRINCIPLES OF THE CLASSICAL ELECTROMAGNETISM AND OF THE UNDULATORY OPTICS.
THE MAIN ACQUIRED KNOWLEDGE WILL BE:
-THE DESCRIPTION AND THE TRATMENT OF THE ELECTRICAL FORCE, FIELD AND POTENTIAL, DUE TO DISCRETE AND CONTINUE CHARGE DISTRIBUTION
-THE CHARACTERISTICS OF THE ELECTRICAL CURRENT, RESISTANCE AND CAPACITY, BOTH FROM THE MACROSCOPIC AND MICROSCOPIC POINT OF VIEW, AND THE ELETRICAL CIRCUIT ANALYSIS
-THE MAGNETIC FIELD, ITS PRODUCTION, ITS ASSOCIATED ENERGY, AND ITS INTERACTION WITH THE MATTER
-THE ELECTROMAGNETIC WAVES, THEIR CHARACTERISTICS AND PROPAGATION IN THE SPACE
-THE BASIC OF THE THEORY OF ERRORS, OF THE EXPERIMENTAL DATA ANALYSIS, OF THE COMBINATORIAL CALCULUS, OF THE PROBABILITY DISTRIBUTION FUNCTIONS, AND OF THE STATISTICAL TREATMENT OF THE RESULTS OF THE MEASUREMENTS
THE MAIN SKILLS THAT WILL BE DEVELOPED WILL BE:
-THE ABILITY TO UNDERSTAND/LEARN AUTONOMOUSLY THE RELATIVE ADVANCED CONCEPTS (PHYSICO-CHEMICAL)
-THE ABILITY OF MODELLING REAL SYSTEMS MADE BY ELECTRICALLY CHARGED OBJECTS, OR IN PRESENCE OF ELECTRIC CURRENT, OR WITH MAGNETIC MOMENTUM/PROPERTIES
-THE POSSIBILITY TO FACE THE RESOLUTION OF APPLICATIVE (PHYSICO-CHEMICAL) PROBLEMS CONCERNING THE CLASSIC ELECTROMAGNETISM
-THE RIGHT VOCABULARY TO PRESENT IN A CRITICAL WAY THE ACQUIRED KNOWLEDGE
- THE COMPETENCE IN PERFORMING SIMPLE EXPERIMENTS, IN THE FIELD OF MECHANICS AND ELECTROMAGNETISM, BEING ABLE TO EVALUATE AND TREAT APPROPRIATELY THE ERRORS AND TO ANALYSE WITH A STATISTICAL APPROACH THE OBTAINED EXPERIMENTAL DATA

Teaching Methods
THE COURSE IS ORGANIZED IN 84 HOURS OF CLASSROOM LECTURES, EXERCISE/EXAMPLES AND LABORATORY LECTURES (8 CFU). FOR WHAT CONCERNS THE EXPERIMENTS IN LABORATORY ONLY, IT IS NECESSARY TO ATTEND THEM, AND THE PRESENCE OF THE STUDENTS WILL BE VERIFIED PERSONALLY BY THE PROFESSOR, AT THE BEGINNING OF EACH LESSON. THE STUDENTS WILL BE DIVIDED IN GROUPS (TIPICALLY MADE UP OF 3 TO 5 STUDENTS) AND WILL PERFORM THE EXPERIMENTS UNDER THE CONTROL OF THE PROFESSOR AND BY INTERACTING WITH HIM IN ORDER TO DISCUSS ABOUT THE PROBLEMS ENCOUNTERED DURING THE EXPERIMENTS AND ABOUT EVENTUAL DOUBT TO SOLVE. AT THE END OF ANY LABORATORY SESSION, EACH GROUP WILL HAVE TO PRODUCE A REPORT THAT MUST BE SUBMITTED TO THE PROFESSOR BEFORE THE NEXT LABORATORY SESSION.
Verification of learning
THE ACQUIRED KNOWLEDGE IS CERTIFIED FIRST BY A WRITTEN AND THEN BY AN ORAL EXAM. IN PARTICULAR:

-FOR THOSE STUDENTS WHO ATTEND WITH PROFIT THE LECTURES, TWO WRITTEN PROOFS ARE PLANNED DURING THE COURSE. EACH PROOF CONSISTS OF A SERIES OF EXERCISES. THOSE STUDENTS WHO OBTAIN AT LAST 18/30 POINTS CAN – BUT NEED NOT – BYPASS THE FINAL WRITTEN EXAMINATION. THOSE STUDENTS WHO OBTAIN AT LAST 27/30 POINTS CAN – BUT NEED NOT – BYPASS THE FINAL WRITTEN AND ORAL EXAMINATION ABOUT THEORY, BUT HAVE TO BE EVALUATED FOR WHAT CONCERNS THE LABORATORY ACTIVITY.

-FOR THOSE STUDENTS WHO DID NOT ATTEND WITH PROFIT THE LECTURES OR DID NOT ATTEND THE LECTURES AT ALL: ONE WRITTEN PROOF WITH PROBLEMS. AT LAST 15/30 POINTS ARE NEEDED FOR THE ADMITTANCE TO THE ORAL EXAMINATION. THOSE STUDENTS WHO OBTAIN AT LAST 27/30 POINTS CAN – BUT NEED NOT – BYPASS THE FINAL WRITTEN AND ORAL EXAMINATION ABOUT THEORY, BUT HAVE TO BE EVALUATED FOR WHAT CONCERNS THE LABORATORY ACTIVITY.

THE ORAL EXAMINATION IS INTENDED TO BE COMPREHENSIVE OF THE EVALUATION OF THE LABORATORY PROOFS, AND OF ALL THE CONCEPT OF ELECTROMAGNETISM AND OPTICS INDICATED IN THE PROGRAM OF THE COURSE. THE FINAL POINTS WILL DEPEND ON THE POINT RECEIVED AT THE WRITTEN AND ORAL EXAMINATIONS, AND ALSO THE REPORTS PRODUCED FOR EACH EXPERIMENT IN LABORATORY WILL BE EVALUATED.
FOR THE LABORATORY COURSE A MINIMUM (2/3 OF THE LECTURES) NUMBER OF PRESENCES IS REQUIRED TO HAVE ACCESS TO THE FINAL ORAL EXAMINATION. THIS FINAL EXAMINATION MUST BE TAKEN NOT LATER THAN 2 ACADEMIC YEARS WITH RESPECT TO THE ACADEMIC YEAR WHEN THE LABORATORY COURSE WAS ATTENDED. AFTER THESE 2 ACADEMIC YEARS, IT WILL BE NECESSARY TO ATTEND AGAIN THE LABORATORY COURSE IN ORDER TO HAVE ACCESS TO THE FINAL EXAM.
