This course covers aspects of physics that can all be described through an understanding of oscillations and waves. We start with a description of harmonic motion and learn how simple models of single and coupled oscillators can be used to find useful descriptions of many physical systems. We also introduce the Lagrangian as a tool for finding equations that can model complicated mechanical systems. Coupled oscillations are generalised into waves and we will discuss the abundance of waves in physics. Fourier theory is then introduced. This powerful concept allows the treatment of vibrations and waves in the frequency domain, in turn allowing analysis of complicated systems of waves where the behaviour may depend of the frequency of the wave. In this way we discover wave dispersion and its applications. Finally, particular attention is paid to light waves. We cover aspects of optics including polarisation, interference, interferometry and diffraction. The course material is supported throughout by examples taken from recent research on mechanical systems, nano-optics, atomic physics, biological systems and laser physics. Computer models provide an opportunity to explore various concepts presented in lectures, including coupled linear oscillators and chaotic dynamics in driven non-linear oscillators. Complementing the lectures, this course contains a laboratory component. Some experiments are essentially qualitative and support lecture material, while others allow development of important skills in quantitative experimental physics.
Upon successful completion, students will have the knowledge and skills to:
On satisfying the requirements of this course, students will have the knowledge and skills to:
- Understand systems of single and multiple harmonic oscillators and appreciate the role of driving, damping and coupling of harmonic systems.
- Identify systems that can be understood using simple models of harmonic oscillation and thereby understand a range of physical systems with a single unified model.
- Understand the role of the wave equation and appreciate the universal nature of wave motion in a range of physical systems.
- Understand optical phenomena such as polarisation, birefringence, interference and diffraction in terms of the wave model.
- Understand a diffraction and imaging in terms of Fourier optics and gain physical and intuitive insight in a range of physics via the spatial Fourier Transform.
- Through the lab course, understand the principles of measurement and error analysis and develop skills in experimental design.
Assessment will be based on:
- Four assignments (20%; LO 1-5)
- Laboratory work (30%; LO 6)
- Final exam (50%; LO 1-5)
The ANU uses Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. While the use of Turnitin is not mandatory, the ANU highly recommends Turnitin is used by both teaching staff and students. For additional information regarding Turnitin please visit the ANU Online website.
Approximately twenty-four lectures, up to twelve tutorials and twenty-four hours of laboratory work, plus individual study.
