Synopsis:

The course Physics 2 is closely linked with the course Physics 1. Within the framework of this course the students will first of all learn foundations of phenomenological and statistical thermodynamics. Following topic - the theory of waves - will give to the students basic insight into the properties of waves and will help to the students to understand that the presented description of the waves has a universal character in spite of the waves character. Particular types of waves, such as acoustic or electromagnetic waves are the subjects of the following section. Quantum mechanics physics will complete the student´s general education in physics. The knowledge gained in this course will help to the students in study of modern technical areas encountered during their studies and will allow them to understand the principles of novel technologies and functioning of new electronic devices.
