Learning outcomes of the course unit
The knowledge of laws of modern physics and ability to apply the basic principles to simple physical systems in order to explain and predict the behaviour of such systems.
Prerequisites
Knowledge of Newtonian mechanics, oscillations, electromagnetism and optics on the level defined by the textbook HALLIDAY, D. – RESNICK, R. – WALKER, J. Fundamentals of Physics. J. Wiley and Sons.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes
The exam is combined (written and oral).
Aims
The course objective is to provide students with basic ideas of modern physics in order to be capable of understanding microscopical nature of matter and principles, which the advanced materials technologies and modern experimental methods are based on.
Specification of controlled education, way of implementation and compensation for absences
Attendance at seminars is required and recorded by the lecturer. Missed seminars have to be compensated.
