Objectives
THE COURSE PROVIDES THE BASIC FORMATION IN THE FIELD OF CLASSICAL ELECTROMAGNETISM AND OPTICS.

KNOWLEDGE AND UNDERSTANDING:
AT THE END OF THE COURSE THE STUDENT WILL KNOW:
-THE MOST IMPORTANT PHENOMENA CONNECTED WITH THE EXISTENCE OF ELECTRICAL CHARGES AND THE ELECTROMAGNETIC FIELDS, BOTH IN VACUUM AND IN MATERIAL MEDIA, AND THEIR INTERPRETATION IN TERMS OF THE MODERN ATOMIC PHYSICS;
- THE ELECTRIC AND THE MAGNETIC FIELD PRODUCED BY TYPICAL DISTRIBUTIONS OF CHARGES AND CURRENTS, RESPECTIVELY;
HE WILL HAVE AN ADEQUATE INTRODUCTION TO THE STUDY OF MECHANICS WAVES AND OF THE MOST RELEVANT RELATED PHENOMENA;
HE WILL HAVE AN INTERMEDIATE LEVEL KNOWLEDGE OF THE MAXWELL EQUATIONS, THE ELECTROMAGNETIC WAVES AND UNDULATORY OPTICS;

ABILITY TO APPLY KNOWLEDGE AND UNDESTANDING
-AT THE END OF THE COURSE THE STUDENT WILL BE ABLE TO: CALCULATE THE ELECTIC FIELD PRODUCED BY TYPICAL CHARGES DISTRIBUTION;
ANALYZE THE FUNDAMENTAL ELECTRIC CIRCUITS;
CALCULATE THE MAGNETIC FIELD PRODUCED BY TYPICAL CURRENT DISTRIBUTION;
CALCULATE THE MOST RELEVANT EFFECTS PRODUCED BY THE ELECTROMAGNETIC INDUCTION;
CALCULATE, IN SIMPLE CASES THE EFFECTS OF WAVES INTERFERENCE AND DIFFRACTION AND OF THE DOPPLER EFFECT;
-MORE IN GENERAL, HE WILL BE ABLE TO SOLVE EXERCISES AN PROBLEMS OF ELECTROMAGNETISM AND OPTICS, AT INTERMEDIATE LEVEL.

Teaching Methods
THE COURSE INCLUDES THEORETICAL LESSONS AND CLASSROOM EXERCISES. DURING THE EXERCISES, THE STUDENT IS ASKED TO SOLVE PROBLEMS RELATED TO ELECTROMAGNETISM. THE SOLUTION STRATEGY REQUIRES: UNDERSTANDING THE PROBLEM, PLANNING THE SOLUTION, AND FINALLY SOLVING IT. THIS LAST PHASE PROMOTES THE ABILITY TO EVALUATE THE CORRECTNESS OF THE RESPONSE AND TO VERIFY THE CONSISTENCY WITH THE FUNDAMENTAL PRINCIPLES OF ELECTROMAGNETISM.
Verification of learning
THE FINAL EXAM IS CONSTITUTED BY TWO PARTS. ONE WRITTEN PART AIMS TO EVALUATE THE ABILITY OF THE STUDENTS IN SOLVING EXERCISES ABOUT ARGUMENTS PRESENTED DURING THE COURSE. IN PARTICULAR, THE STUDENT CAN BE REQUESTED TO COMPUTE THE ELECTRIC OR THE MAGNETIC FILD PRODUCED BY SOME DISTRIBUTION OF CHARGES OR CURRENTS, RESPECTIVELY. IN SOME OTHER CASE, THE STUDENT CAN BE REQUESTED TO SHOW TO BE ABLE TO APPLY THE LAWS DESCRIBING THE INTERACTION BETWEEN ELECTRIC CHARGES, OR BETWEEN CURRENTS, OR BETWEEN MAGNETIC FIELDS AND ELECTRIC CHARGES. THE STUDENT SHOULD BE ABLE TO ANALYZE SIMPLE ELECTRIC CIRCUITS, AND TO CORRECTLY APPLY THE FARADY INDUCTION LAW. MOREOVER, THE STUDENT CAN BE REQUESTED TO COMPUTE THE EFFECTS OF WAVES INTERFERENCE, OR THOSE OF THE DOPPLER EFFECT. A SECOND ORAL PART, WHERE THE STUDENTS WILL BE INVITED TO PRESENT SOME TOPICS PRESENTED DURING THE COURSE,IN ORDER TO EVALUATE THEIR LEARNING, COMPREHENSION, AND CORRECT EXPOSITION SKILLS. THE WRITTEN PART HAS THE DURATION OF TWO HOURS AND REGARDS THE SOLUTION OF FOUR EXERCISES OR SIMPLE PROBLEMS ON ARGUMENTS PRESENTED IN THE COURSE. THE EVALUATION IS EXPRESSED IN THIRTIETHS. FOR THE ADMISSION TO THE ORAL EXAM THE MINIMUM MARK IS 18/30. DURING THE WRITTEN PART THE CONSULTATION OF BOOKS OR NOTES AND THE USE OF COMPUTER ARE NOT ALLOWED. ONLY LITTLE CALCULATING MACHINES CAN BE USED.

THE MINIMUM LEVEL OF EVALUATION (18) IS ASSIGNED WHEN THE STUDENT DEMONSTRATES UNCERTAINTIES TO COMPUTE THE ELECTRIC OR THE MAGNETIC FILD PRODUCED BY SOME DISTRIBUTION OF CHARGES OR CURRENTS, AND/OR TO APPLY THE LAWS DESCRIBING THE INTERACTION BETWEEN ELECTRIC CHARGES, OR BETWEEN CURRENTS, OR BETWEEN MAGNETIC FIELDS AND ELECTRIC CHARGES.

THE MAXIMUM LEVEL (30) IS ASSIGNED WHEN THE STUDENT DEMONSTRATES A COMPLETE AND IN-DEPTH KNOWLEDGE OF THE LAWS DESCRIBING THE INTERACTION BETWEEN ELECTRIC CHARGES, OR BETWEEN CURRENTS, OR BETWEEN MAGNETIC FIELDS AND ELECTRIC CHARGE AND TO COMPUTE THE ELECTRIC OR THE MAGNETIC FILD PRODUCED BY SOME DISTRIBUTION OF CHARGES OR CURRENTS, AS WELL AS TO ANALYZE SIMPLE ELECTRIC CIRCUITS, AND TO CORRECTLY APPLY THE FARADY INDUCTION LAW.

PRAISE IS GIVEN WHEN THE CANDIDATE DEMONSTRATES SIGNIFICANT MASTERY OF THE THEORETICAL AND OPERATIONAL CONTENT AND SHOWS HOW TO PRESENT THE TOPICS WITH CONSIDERABLE MASTERY OF THE SPECIFIC TECHNICAL LANGUAGE AND AUTONOMOUS PROCESSING SKILLS EVEN IN CONTEXTS DIFFERENT FROM THOSE PROPOSED BY THE TEACHER.
