The aim of the module is to provide students with a basic understanding of the fundamentals of optics. Part of the course is concerned with geometrical or ray optics, from the basic principles of reflection and refraction to the properties of lenses and simple optical instruments. Another section deals with physical or wave optics, concerning interference, Fraunhofer and Fresnel diffraction and leading on to polarisation and the optical properties of birefringent crystals. The course ends with an introduction to the modern topics of holography and non-linear optics.
Additional learning activities
Video on Optical Interference.
