Course description  *** Course discontinued as of 2012/13***
This course provides an introduction to classical dynamics, special relativity, geometric optics and the physics of waves. It serves both as a preparation for further study in physicsbased degree programmes, and as a standalone course for students of other disciplines, including mathematics, chemistry, computer science and engineering. The course is supported by a programme of tutorial workshops and includes an introductory module on Java programming and data analysis.

Summary of Intended Learning Outcomes
Upon successful completion of this course, it is intended that a student will understand
 basic Newtonian mechanics;
 how to set up a dynamical system for solution using first and second order differential equations;
 the role and diversity of simple harmonic motion in physics;
 the role of symmetry in simplifying a problem;
 the two basic postulates of Special Relativity;
 the phenomena of time dilation and Lorentz contraction;
 that the notion of simultaneity depends on the reference frame;
 relativistic velocities transformation, linear momentum, and total and kinetic energy;
 that in the low speed limit relativistic results correspond to classical Newtonian physics;
 what is meant a rest mass energy;
 geometric optics using Gaussian lens formula and matrix ray methods;
 basic optical systems, including the human eye, magnifier, telescope, microscope; concepts of optical aberrations and their control;
 types of wave phenomena: standing waves, travelling waves, normal modes, resonance, sound waves;
 superposition of waves. Beats. Harmonics. Acoustics;
 wavefronts. Huyghen's principle. Doppler effect. Shock waves;
 energy storage and transport in mechanical waves. Intensity;
 reflection and transmission of mechanical waves at boundaries;
 dispersion, group and phase velocities. Water waves;
 electromagnetic waves. Spectrum. Speed of light. Red shifts;
 reflection and refraction of light. Total internal reflection;
 energy storage and transport in electromagnetic waves;
 polarisation states. Polarisers.  Interference of light. Two slits. Newton's rings;
 interferometers. Michelson. TwymanGreen. FabryPerot;
 diffraction. Apertures. Gratings;
 dispersion of electromagnetic waves.  Wavepackets. Signal transmission. Introduction to Fourier analysis.
Other course elements: the Data Analysis course will give the ability to manipulate, plot and fit, in a linear form, with error bars, data using spreadsheet software. The Java component will explain the practical utility of computation for solving physical problems and construct Java programs using variables, control structures and supplied routines to model simple physical systems.
