Learning objectives
The course aim is to provide students with theoretical skills and application information of Classic Optics.
The educational objectives are:
that the student follows some of the classical derivations of the laws of optics, starting from first principles.
That the student realizes the connection of optics with the theories of Electromagnetism, Relativity and
Quantum Mechanics.
That the student knows, both from a phenomenological point of view and from a theoretical point of view, the main optical phenomena.
That the student has knowledge and appreciates the applicative potential of the optics.
Expected learning outcomes
The student at the end of the course may have acquired the following skills:
1. place the optical phenomena within the framework of the more general electromagnetic phenomena;
2. know the laws of reflection and refraction as an example of application of the conditions to the
contour of electromagnetic fields and knowing their most common applications;
4. know the Drude-Lorentz model and analyze the dispersion of a dielectric medium;
5. recognize some of the most common phenomena related to dispersion and absorption;
6. know the problem of the speed of light, its experimental bases and its relativist treatment;
7. know the various types of interferometers and their applications in radiation diagnostics;
8. know the details of the diffraction theory and its most important applications;
10. know the problem and the laws of coherence with related applications.
