| Aim: The course consists of two parts, Modern and Classical Physics. Modern Physics will give an orientation about the physics of the 20:th century. The aim is to present the basic ideas of modern physics and to give examples of how these often abstract theories influences or explains phenomena observed in our everyday life. The Classical Physics gives an introduction to thermodynamics and wave theory. Basic concepts of the thermodynamics and wave theory will be presented as well as some basic applications related to the subject. Experimental techniques will be used to study wave phenomena. Experimental problem solving including problem formulation, dimensional analysis and error calculation is also included in the course. Supplementary courses: TMMV15 Fluid Mechanics and Heat TransferCourse organization: Modern Physics consists of 26 h lectures, 10 h seminars and 8 h laborations. The classical part consists of 26 h lectures, 40 h seminars and 24 h laborations.Course content: The status of classical physics from the late 19:th century are briefly discussed as a comparison to the thinking of the modern physics. We start with the Einstein theory of special relativity and continue with the model for the atom nuclei. We discuss nuclear reactions, decay and radioactivity. The use of nuclear fission for energy production and nuclear fission in the sun are explained. The biological impact of ionized radiation are also covered. The development of quantum mechanics are described via the Bohr model of the hydrogen atom, the de'Broglie hypothese about wave-particle dualism , and the Schrödinger wave equation, one-electron systems, quantum numbers, energy levels, atomic spectra, multi-electron atoms, Pauli principle, the periodic table of elements, lasers. Applications related to electronic levels, their use and physical explanation, such as x-rays, lasers and electron microscopes are described. Within solid state physics we discuss different bondings between atoms, lattice structures, the band model for metals, isolators and semiconductors. The effect of doping of semiconductors and thermal and electrical properties of solids. The Classical Physics part of the course cintains the following material 1. Kinetic gas theory and Thermodynamics Definition of temperature, volume, pressure and internal energy. The ideal gas law, ideal and real gases, collision rate, mean free path. The laws of thermodynamics, specific heat capacity, work, heat exchange, entropy. Isothermal, isobaric, adiabatic, isovolumic processes, thermodynamic processes, heat engines and refrigerators. 2. Waves. Presentation of the basic concepts in wave theory. Harmonic motion, energy transport, wave impedance, interference, longitudinal and transverse waves. Standing waves. Reflection absorption and transmission. Polarisation, interference and diffraction, Brewster's law, active optics, the doppler effect, acoustic waves. 3. Measurement technology. Introduction to measurement technology. Experimental techniques will be used to study wave phenomena. Course literature: Halliday, Resnick Walker: Fundamentals of Physics. Instructions to experiments. | ||
