Overview

The student should have acquired the elements of alternating currents, electromagnetic waves, wave propagation and geometrical optics, interference and diffraction, polarization.

The student should be able to apply the knowledge acquired for problem solving regarding the alternating currents, electromagnetic waves, wave propagation and geometrical optics, interference and diffraction, polarization.

The student at the end of the course should be able to describe with the appropriate technical language and mathematical formalism the topics presented in the course.

Admission requirements

Not mandatory: basics of mechanics, thermodynamics and electromagnetism from first year courses.

Teaching methods

Lectures numerical exercises and tutoring in person or, in the event of a pandemic, online Optional attendance. Methods for working students: working students who cannot attend lessons communicate this to the teacher and can study the topics in the recommended textbooks and any teaching material distributed. Reception hours: Monday 14-16 Thursday 14-16 Physics building, studio on the first floor or by appointment requested by e-mail

Assessment methods

Written exam: solution of a problem for each of the three areas of the course: mechanical waves; electromagnetic waves; geometric optics, interference, diffraction. Oral exam on the course contents

Learning outcomes

Knowledge and understanding:
at the end of the course, the student must have acquired the knowledge of oscillatory and wave phenomena, and be able to understand a vast physical phenomenology including mechanical and electromagnetic waves, interference and diffraction, wave optics and optics geometric.
Ability to apply knowledge and understanding:
at the end of the course, the student will be able to apply the acquired knowledge to the solution of problems related to wave phenomena in general, and to optics in particular.

Autonomy of judgment:
at the end of the course, thanks to the variety of examples provided through the course, the student will have to possess the necessary skill and autonomy of judgment to recognize which methods are the most suitable for solving problems in oscillation and wave physics.

Communication skills
at the end of the course, the student must be able to present in a clear, rigorous and concise way the results of experiments and theories underlying the physics of oscillations and waves.

Learning skills:
The study will allow the development of learning skills and autonomous in-depth study on the topics presented in the course.
