| Outcomes | This unit provides an introduction to modern physics. It is required for students intending to major in Physics and suitable for students undertaking the Bachelor of Science and Bachelor of Engineering combined degree. It is also suitable for students majoring in other subjects who desire a strong physics background. In addition to providing an introduction to many aspects of modern physics, the unit emphasises a number of important unifying themes which underlie what are, at first sight, unrelated physical phenomena. | |||
| Content | Topics include: Relativity—postulates of special relativity, Lorentz transformations, length contraction, time dilation, relativistic dynamics, mass increase, mass–energy relation, energy–momentum relation. Modern physics—wave functions and the Schroedinger equation, tunnelling, spin, Pauli exclusion principle, multi-electron atoms, Zeeman effect, X-ray spectra, nuclei and radioactivity, lasers, atom traps and cooling, Bose-Einstein condensation, astronomy, cosmology. Symmetries and conservation laws—conserved quantities, forces and potential energy, linear momentum, angular momentum and rotations, orbits and scattering in central potentials, chaos, lattice waves and phonons, light scattering and polaritons, quantisation of angular momentum. Resonance phenomena—inductance, LCR circuits, phasors, complex impedance, frequency response, equipartition theorem, frequency response as a Fourier transform, mechanical resonators, fluctuations and dissipation, noise, spectral lines and resonance, electron spin resonance, NMR. | |||
| Assessment | This comprises an examination (50 per cent), three tests during semester (38 per cent) and laboratories (12 per cent). Supplementary assessment is available for those students who obtain a mark of 45 to 49 inclusive in this unit (see University General Rule 1.2.1.25). | |||
