COMPLEMENTI DI FISICA
Academic Year 2024/2025 - Teacher: ROSARIO PIZZONEExpected Learning Outcomes
The approach to describing the systems and phenomena described above will be experimental in nature, and physical theories will be presented in terms of logical and mathematical structure, as well as experimental evidence. By the end of the course, the student will have developed the ability for both inductive and deductive reasoning. They will be capable of conceptualizing a phenomenon in terms of physical quantities and framing and solving problems using analytical methods. The student will apply the scientific method to the study of natural phenomena and will be able to critically evaluate similarities and differences between physical systems and the methodologies to be applied. The outcome will be a deep understanding of the topics of Electricity, Magnetism, and wave phenomena outlined in the course curriculum, as well as the ability to tackle and solve problems related to these subjects.
Course Structure
The course consists of lectures and practical exercises.
During the practical exercises, similar exercises to those in the exam will be solved
Required Prerequisites
For learning and/or independently reinforcing the required preliminary knowledge, basic mathematics and mathematical analysis courses may be helpful. A thorough understanding of the concepts of mechanics and thermodynamics is naturally required.
