Thermodynamics: temperature (incl. measuring temp., thermal expansion, bimetal); equations of state (incl. gas equation, phase diagrams); thermodynamic changes in gas (incl. work during expansion, association between specific heat); energy law (incl. phase changes); heat engines (incl. yields of thermal machines); diffusion of heat (incl. heat conduction, insulation). Optics: wave optics (incl. interference, diffraction of X-rays); geometrical optics (incl. reflection, refraction, total reflection, optical instruments – microscopes, telescopes). Topics in Modern Physics (incl. photoelectric effect, the model of the atom, radioactivity).
