Learning outcomes

This course is the last part of the Introductory physics courses that are part of bachelor's program in physics and chemistry. It aims to provide an understanding of the fundamental concepts, thus laying the foundations for more advanced courses. The course emphasises the importance of rigorous scientific reasoning, as well as the importance of observation and calculation in dealing with physics problems.

Assessment method

The final exam is oral. The student is given 3 questions, one of which is related to wave optics. These questions may include a simple problem (e.g. direct numerical application of the theory). The student prepares the answers (about 1/2 hour per question) and then presents the answer orally. For practical reasons, the examination may be organised in two parts on the same day. Students are expected to use rigourous scientific arguments including appropriate mathematics. They should demonstrate thorough understanding of the physical meaning of the results and be able to present results in a meaningful way, including graphs, tables, and numerical values. In principle, the weight of the three questions is the same in the final mark, but a clearly insufficient answer to one of the questions may lead to the failure of the teaching unit, regardless of the marks obtained for the other questions.
