The laboratories of the Department of physics

The laboratories of the Department of Physics are among the first laboratories the students get acquainted with during their studies. They are situated in the main building of the University. There are three of them: Laboratory of Molecular Physics, Electrical Laboratory and Optical Laboratory.

ш the Laboratory of Molecular Physics students carry out a number of laboratory exercises in mechanics and molecular physics. These exercises illustrate the laws of motion of material objects, principles of mechanical interactions between objects, the laws of vibratory motion. Properties of gases, vapours, liquids and thermal properties of soUds are also studied in this laboratory.

In another laboratory, the electrical one, students study practically the properties of conductors, semiconductors and insulators, the basic laws of electrostatics, the laws describing current flow in separate conductors and in electric circuits, electromagnetic phenomena and the laws of electrolysis.

In Optical Laboratory, students carry out experiments which help them to practically study the laws of geometrical optics and different phenomena connected with the wave nature of light and quantum nature of light (e. g., interference, diffraction, photo-effect). Here they also do some assignments on the investigation of the structure of atom.

Using their knowledge of general laws of physics, students determine moduli of elasticity of different substances, thermal conductivity coefficients, electric field strength, specific resistance, dielectric and magnetic constants of different substances, light wave length etc. Students use modern standard instrumentation. They are: analy­tical balances, manometers, electromagnetic oscillators, ac (alternating current) and dc (direct current) generators, modern precise digital instruments, interferometers, lasers etc.

A thorough fulfilment of laboratory tasks in the Laboratories of the Department of Physics lays the foundation for further successful work when students begin to work in their special laboratories.
