Learning Outcome

After the successful obsolvation of the modul, students know the principles of atomic physics and the applications and are able to apply them to solve given problems. Students understand the methods and concepts of non-relativistic quantum physics and the limitations and can apply them. Students know the principles of atomic electron transitions and the relevance of symmetries e.g. parity symmetry. After the successful particapation in this modul students know the concepts to quantummechnically describe ground states and excitations in molecular physics und apply this knowledge  to two atomic molecules. 

Students know the basic concepts of thermodynamics and understand the physcis behind heat and heat transport. They can describe thermodynamic processes and know the laws of thermodynamics and their application. They know the physics of phase transistions and the thermodynamics of solutions.

Module Exam

Description of exams and course work

There will be a written exam of 90 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using calculation problems and comprehension questions. The exam is in german.

For example an assignment in the exam might be:

  • Sketch a qualitatively correct energy scheme of hydrogen with and without fine structure up to n=2.
  • Calculate and compare the absorbtion frequencies of the three hydrogen isotopes Protium, Deuterium and Tritium of the Lyman-α-linie.
  • Gas with a given volume is heated by 600 K. Calculate the work W and the heat Q for this process.

Participation in the exercise classes is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.

There will be a bonus (one intermediate stepping of "0,3" to the better grade) on passed module exams (4,3 is not upgraded to 4,0). The bonus is applicable to the exam period directly following the lecture period (not to the exam repetition) and subject to the condition that the student passes the mid-term of

  • passing the voluntary test exam during the semester
  • sensibly preparing at least 50% of the problems for presentation in the tutorials

Exam Repetition

The exam may be repeated at the end of the semester.
