Course Description:
STUDENTS ARE EXPECTED TO HAVE COMPLETED First semester Algebra and Calculus courses and knowledge on single particle dynamics. COMPETENCES AND SKILLS THAT WILL BE ACQUIRED AND LEARNING RESULTS. This course should make the student familiar with the basics concepts of electromagnetism. Since this is a first year course one of the main goals is to develop the student abilities in understanding abstract physical concepts through the combination of lectures, experiments and problem solving with the aid of mathematical tools. In order to achieve this goal, the following competences and skills have to be acquired: - Disposition to learn and comprehend new abstract concepts. - Ability to understand and use the mathematics involved in the physical models. - Ability to understand and use the scientific method. - Ability to understand and use the scientific language. - Develop abilities in problem solving. - Ability to use scientific instruments and analyze experimental data. - Ability to retrieve and analyze information from different sources. - Ability to work in a team.

Electromagnetic waves LEARNING ACTIVITIES AND METHODOLOGY Lectures, where the theoretical concepts are explained The lecturer provide a file with the following information (1 week in advance) - Main topics to be discussed during the session - Chapters/sections in each of the text books provided in the bibliography were the student can read about these topics Recitations (~ 40 students divide in 2-3 people groups) to solve problems. The main skills to be developed in these activities are: - To understand the statement of the problem (for instance drawing an scheme that summarizes the statement) - To identify the physical phenomenon involved in the statement and the physical laws related to it. - To develop a strategy to reach the objective (for instance breaking the problem in small sub-problems). - To be careful in the use of mathematics - To analyze the result (is the final number reasonable?, are the dimensions consistent?) Small works focused to the search of scientific information in different sources (mainly internet). Laboratory sessions (~ 24 students divide in 2 people groups) The main skills to be developed in this activity are: - To understand that physics is an experimental science and they can reproduce the laws that have been theoretically explained in the lectures - To use scientific instruments and to be careful in its operation - To be careful in the acquisition of the experimental data - To learn the basis of the management of a scientific data set - To write a report with the main results of the experiment - To reason in a critical way these results: have we achieve the goals of the experiment? Página 2 de 3 ASSESSMENT SYSTEM Despite the final mark is obtained with the percentages indicated bellow, attendance to the laboratory sessions is COMPULSORY to pass the course. Additionally, it is OBLIGATORY to obtain at least a score of 3 out of 10 in the final exam to pass the course. Laboratory sessions (15% of final mark) Evaluation based on: - Attendance to the laboratory sessions, participation and attitude. Activities in groups of two students. - Laboratory reports quality. Mark is shared by the members of the group. Recitation groups (25% of final mark). Evaluation based on: - Attendance. - Short test exams. - Delivery and quality of proposed activities Written exam (60% of final mark) This exam is made at the end of the semester and it is the same for all the students Consists in: - Problem solving covering the topics of the program and perhaps - Short theoretical questions % end-of-term-examination: 60 % of continuous assessment (assigments, laboratory, practicals…): 40 BASIC BIBLIOGRAPHY - Alan Giambattista, Betty McCarthy Richardson and Robert C.
