BASIC AND GENERAL
CB1 - That students have demonstrated to possess and understand knowledge in an area of study that starts from the base of education
general secondary school, and is usually found at a level that, while supported by advanced textbooks, also includes some aspects that
they imply knowledge coming from the vanguard of their field of study.
CB2 - That students know how to apply their knowledge to their work or vocation in a professional manner and possess the skills that are usually
demonstrate by means of the elaboration and defense of arguments and the resolution of problems within their area of study.
CB3 - That students have the ability to gather and interpret relevant data (usually within their area of study) to issue
judgments that include a reflection on relevant social, scientific or ethical issues.
CG1 - Possess and understand the most important concepts, methods and results of the different branches of Physics, with a historical perspective of their development.
CG2 - Have the ability to gather and interpret relevant data, information and results, obtain conclusions and issue reasoned reports
in scientific, technological or other problems that require the use of knowledge of Physics.
CG3 - Apply both the theoretical and practical knowledge acquired as well as the capacity for analysis and abstraction in the definition and
approach of problems and in the search of their solutions both in academic and professional contexts.
TRANSVERSALS
CT1 - Acquire analysis and synthesis capacity.
CT2 - Have the capacity for organization and planning.
CT5 - Develop critical reasoning.
SPECIFIC
CE1 - Have a good understanding of the most important physical theories, locating in their logical and mathematical structure, their support
experimental and the physical phenomenon that can be described through them.
CE2 - Be able to clearly handle orders of magnitude and make appropriate estimates in order to develop a clear perception of
situations that, although physically different, show some analogy, allowing the use of known solutions to new problems.
CE3 - Be familiar with the most important experimental models, besides being able to perform experiments independently,
as well as describe, analyze and critically evaluate the experimental data.
CE4 - Be able to compare new experimental data with available models to check its validity and suggest changes that improve the
concordance of the models with the data.
CE5 - Be able to perform the essentials of a process or situation and establish a working model of it, as well as perform the approximations
required in order to reduce the problem to a manageable level. He will demonstrate critical thinking to build physical models.
CE6 - Understand and master the use of mathematical and numerical methods most commonly used in Physics
CE7 - Be able to use computer tools and develop software programs
CE8 - Be able to manage, search and use bibliography, as well as any source of relevant information and apply it to research and technical development of projects
A course will be activated on the Moodle platform of the Virtual Campus, to which information of interest to the student will be uploaded, as well as diverse teaching material.
The general methodological indications established in the USC Degree Physics Report will be followed. Classes will be face-to-face and the distribution of expository and interactive hours follows that specified in the Grade Report.
The tutorials may be face-to-face or telematic, if they are telematic they will require an appointment, which is also recommended for face-to-face.
For the evaluation of the student, the following aspects will be taken into account:
1) Written exam on theory, questions and problems, on the date set in the exam calendar of the center.
2) Completion of non-classroom activities (homework and laser-related work).
3) Completion of practical classroom exercises (blackboard or written tests).
At the first opportunity, the student may choose a continuous evaluation based on points 2) and 3).
If opting for this evaluation system, the final grade will result from the weighting of these points (60% + 40%).
If they do not choose or do not pass the continuous assessment, the student must take the final exam, point 1), to pass the subject. In this case, the student's grade will correspond to the maximum of the following two options:
i) The grade obtained in the written exam
ii) The grade obtained in the written exam weighted by 60%, plus the score resulting from continuous assessment, weighted by 40%.
The student's grade in the second opportunity will correspond to the grade obtained in the corresponding official exam.
In cases of fraudulent performance of exercises or tests, the provisions of the Regulations for the evaluation of student academic performance and review of grades will apply.
Lectures 45 h
distributed as: master classes 24 hours, seminars 18 hours, tutorials 3 hours
Individual Work
It is recommended what is indicated in the Memory of the Degree Degree in Physics of the USC, without counting the time allocated to face-to-face or telematic teaching, about 60 hours for a subject of 4.5 ECTS.
- To have been, or to be, registered in the matter of Optics I and II and Quantic Physics I and II of the Degree in Physics.
- To perform all the suggested exercises.
- Consultation of the recommended bibliography.
