The Lab serves as an introduction to the methods of experimental work. Students typically carry out 3 various experiments during one semester. Each experiment lasts 20-30 hours. 
The available experiments (for the complete list see below) cover various branches of classical physics (mechanics, electromagnetism, optics, statistical physics) and atomic, molecular and solid state physics as well. The topics vary from modern versions of the famous historical experiments (e.g. Millikan or Franck-Hertz experiments) to many typical or important phenomena (e.g. light interference and diffraction, X-ray diffraction, properties of semiconductors, velocity of light).

Purpose

• to familiarize students with the observed physical phenomena
• practical training in experimental techniques
• practice in analysing and processing experimental data
• developing information finding skills
• developing communication skills (writing reports on the experiments)

Methods

Students are supposed to work on their own i.e. to plan, prepare, and perform the experiments. They have to analyse their results and finally to present a detailed written report of their work. At each stage of their activity they are helped and supervised by the staff members.
