The subject "Waves and Optics" is part of the set of General Physics subjects in the first year of the degree in Physics. This set of subjects is intended:
In this subject we intend to teach both qualitatively and quantitatively the way of reasoning to understand aspects of the world around us and develop skills in problem solving. These skills and knowledge are concretized in the fields of Waves and Optics. It is intended that students acquire the basic concepts of the subjects that form part of the subject, insisting above all on phenomenological aspects and bearing in mind that students will later take other subjects, where they will already have all the appropriate tools to properly develop formalism, and without forgetting the historical context of progress in the different branches of physics, the experiments carried out, and the theories to which they have given rise.
1.- Oscillations
- Simple harmonic oscillatory movement. Oscillator energy.
- The simple pendulum. The physical pendulum. The torsion pendulum.
- Damped oscillations. Forced oscillations. Resonance frequency.
2.- Waves
- Wave movement. Propagation speed. Amplitude. Wave front.
- Longitudinal and transverse waves. Polarization.
- Wave equation. Harmonic waves. Phase and phase difference. Energy and intensity.
- Sound. Propagation speed. Intensity. Decibels. Ultrasounds. The ear.
- Doppler effect.
- Superposition principle. Interference. Superposition of waves of the same frequency. Superposition of waves of different frequency. Stationary waves. Harmonic analysis and synthesis.
3.- Light
- Light as an electromagnetic wave. Plane waves.
- Propagation of light. Principle of Huygens. Principle of Fermat.
- Polarization. Dichroism. Brewster angle. Birefringence.
- Refraction and reflection on a flat surface. Fibers.
- Absorption and diffusion.
4.- Formation of images in the geometric approximation.
- Fundamentals of geometric optics.
- Formation of optical images. Paraxial optics. Lenses and mirrors.
- Optical instruments: principles, geometric relations and utility.
5.- Interferences and diffraction
- Coherence and interferometers.
- Diffraction of a slit. Young's double slit (interferences and diffraction). The diffraction gratting. Fraunhofer and Fresnel diffraction.
Theory lectures:
Although the theory lectures will be master classes, an attempt will be made to introduce, at specific moments, questions that give rise to a certain debate, comments and discussions that allow students to focus their attention on specific points and detect the follow-up of the lectures. There will also be exercises to clarify some theoretical aspects and practical demonstrations of some simple physical phenomena to illustrate or explain the theoretical aspects. In order to do this, the physical phenomena of Optics give us many possibilities to visualize the phenomenon being studied or to be explained.
Exercises lectures:
In these lectures, problems and questions will be posed in such a way that the students solve them on the blackboard individually or in a group, trying to give all the necessary explanations for their correct solution and interpretation. If necessary, the professor will complete and correct everything he considers necessary.
Seminars:
Throughout the course there will be four seminars with the active participation of the students, where physical questions and phenomena related to the subjects being studied will be discussed, both from a historical point of view and from the current applications of the field.
Autonomous work:
The student's autonomous work required in this subject includes both the study of theoretical concepts and the preparation and resolution of exercises and problems. The delivery of problems represents an activity supervised by the teacher and will be evaluated.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

The evaluation will consist of:
In order to pass for partial exams, a minimum score of 3 out of 10 must be obtained in both partial. Students may take the retaken exams if they have previously taken both partial exams.
All those students who have taken the two partial exams and/or the retaken exam cannot be qualified as "Non evaluable".
