Subject: PHYSICS (A.A. 2023/2024)
The course aims to extend student’s knowledge to fundamental aspects of Nature phenomena and the laws of physics behind them. Students will also learn the use of math as instrument of quantitative understanding of physical phenomena.
Students are encouraged to attend Basic courses of vector algebra and differential and integral calculus.
1. Physical quantities. Vectors .(4 ore 0.5 cfu) (12 ore 1,5 cfu) . Kinematic of point. Forces and Newton‘s laws of motion. Circular motion. Work and Energy.
2. Electricity and (18 ore 2 cfu) . Electrostatics. Electric Field. Gauss Law. Electric potential. Capacitance and dielectrics. Current and electrical resistance. DC circuits. Magnetic fields. Faraday’s law. Inductance. Electromagnetic waves.
3. Elements of modern (16 ore 2 cfu) . Wave-particle duality for the electromagnetic radiation. Black body spectrum. Planck’s hypothesis. Photoelectric effect. Photons. The Bohr’s model for the hydrogen atom. The energy bands in solids. Semiconductors: band structure, doping, electric properties.
Course taught in presence and in italian language. Attendance is not mandatory, but strongly recommended. Classroom lectures, problem solving, computer-aided simulations of experiments, real experiments shown through movies. Students engaged in working activities are suggested to contact the course teacher.
9 sessions fo written or oral (under student's request) examination sessions. The oral examination includes the solution of an exercise chosen from a collection of exercises with solution published on the Moodle platform of the present Academic Year and two questions on topics included into the Syllabys published on Moodle of the present Academic Year. Each of the three sections contributes to 1/3 of the final exam mark. Whatever choice for the exam by the student, the numerical analysis of a case study will test the student's attitute to apply math concepts to implement theoretical aspects and obtain a quantitative description of the physical phenomena. The remaining part of the exam will access the student's understanding of the fundamental concepts and laws of classical physics to describe macroscopic phenomena. Graduation policy: 18/30 minimal theoretical skills, attitude to plan a solution strategy to solve the proposed problem; intermediate graduation (18/30-26/30) good-level theoretical skills, attitude to plan the correct solution strategy to solve the proposed problem, identification of the solution path; high graduation (27/30-30/30 e Lode) high-level theoretical skills, ability to plan a solution strategy to solve the proposed problem and to solve it numerically.
Knowledge and comprehension: students get the main concepts of classic (mechanics, electromagnetism) and modern Physics through class lectures.
Application of the concepts to real problems: the application of physics concepts to real problems is demonstrated through examples during lectures.
Independent analysis: through the lecture students become able to formulate questions about Physical theories and to discuss the answers.
Communication abilities: the acquisition of a proper terminology make students able to express and discuss Physics problems.
Learning ability: concepts and methodologies acquired during the course help the student to proceed in his study on a sound basis and keep their knowledge updated.
