Course detail

General Physics III (Vibrations, Waves and Optics)

FSI-TF3Acad. year: 2023/2024

Vibrations, waves and optics is a lecture trying to unify physical phenomena as periodic motion, oscillations and waves in different parts of physics as in mechanics, acoustics, electricity and especially in optics. To understand the lecture it is necessary to be familiar with the introductory lectures Mechanics and molecular physics and Electricity and magnetism. The optics covers all fundamental chapters of basic university course.
