Module overview
It will arm students with a basic knowledge of optics, including ray propagation, polarization and diffraction, and introduce the dual wave and particle characteristics of light and matter. It provides a base for further study of optics, wave physics and quantum physics in subsequent courses.
Aims and Objectives
Learning Outcomes
Subject Specific Intellectual and Research Skills
Having successfully completed this module you will be able to:
- Work with energy and momentum for photons and define a wavelength for a particle, both nonrelativistic and relativistic
- Describe interference and diffraction for slits, gratings and interferometers
- Describe wave superposition and interference, Huygens' construction, Fermat's principle and their application
- Describe polarisation effects and how to create and manipulate polarisation
- Apply the ray propagation model to mirrors, lenses and optical systems built from these, including analysing systems using propagation matrices
- Discuss experiments showing that light and matter can both behave as waves or particles
Syllabus
- Basics of wave motion.
- Rays and images: Huygens' construction and Fermat's principle, rays and propagation matrices.
- Geometrical optics: mirrors, lenses, simple optical systemes (magnifier, telescope, microscope).
- Dispersion and polarisation: prisms, rainbows, polarisation, polarisers, birefringence.
- Wave phenomena: superposition and interference, diffraction; slits, gratings and interferometers.
- Quanta and wave-particle duality: photon energy and momentum, de Broglie waves, electron diffraction, wavepackets and uncertainty, quantum wavefunction.

Assessment
Assessment strategy
Course work worth 20% of the module mark will be set and assessed in the normal way. In the event that a course work is missed, students will be required to go through the Special Considerations procedures in order to request mitigation for that piece of course work. Please note that documentary evidence will normally be required before these can be considered.
A Mid-Semester test will be set approximately half way through the semester worth 10% of the module mark.
The final exam is worth 70% of the module mark.
Referral Method: By examination, the final mark will be calculated both with and without the coursework assessment mark carried forward, and the higher result taken.
Summative
This is how we’ll formally assess what you have learned in this module.
| Method | Percentage contribution |
|---|---|
| Examination | 70% |
| Weekly Online Problem sets | 20% |
| Mid-Semester Test | 10% |
Referral
This is how we’ll assess you if you don’t meet the criteria to pass this module.
| Method | Percentage contribution |
|---|---|
| Coursework marks carried forward | 30% |
| Examination | 70% |
Repeat
An internal repeat is where you take all of your modules again, including any you passed. An external repeat is where you only re-take the modules you failed.
| Method | Percentage contribution |
|---|---|
| Coursework marks carried forward | 30% |
| Examination | 70% |
