Fundamentals of special relativity theory - light velocity independence on the observer's motion, length contraction, time dilation, simultaneity of events, Lorentz transformation, mass and energy relation, Čerenkov radiation. 3. Quantum physics - Wave-particle duality, photoelectric effect, emission and absoption of light quantum, X-Ray and its diffraction. 4. Compton effect, red shift, de Broglie's hypothesis, Davisson-Germer experiment, Estermann-Stern-Frisch experiment. Heisenberg uncertainty principle. 5. Fundamentals of quantum theory - wave function, Schrödinger equation, physical quantity operators and their commutators. 6. Harmonic oscillator, potential hole, tunneling effect. 7. Many-electroc atoms, quantum numbers, periodic table of elements, rules for the electronic level occupation (Pauli exclusion principle, Hund rule). 8. Proof of electron's spin - Stern-Gerlach experiment. Selection rules for spectral lines, their splitting in external magnetic field - normal and anomal Zeemann effect. 9. Statistical physics, fundamentals of quantum statistics, black-body radiation, Rayleigh-Jeans law, Planck radiation law. 10. Statistical distribution for quantum particle systems - bosons and fermions (Bose-Einstein and Fermi -Dirac distribution), specific heat of solid state. 11. Physics of solid state - Atom models, Thompson model, Rutherford scattering experiments, Bohr model of hydrogen atom. 12.
