## Electromagnetism and Optics

**Electromagnetism and Optics**. Instructor: Dr. Martin Smalley. The central aim of this course is to understand how Maxwell unified electricity, magnetism and optics into electromagnetic theory. Knowledge of the basic phenomena of electromagnetism, and a good understanding of the mathematics of vector fields, are essential in achieving the central aim. Maxwell's four equations describe all of electromagnetism, including the propagation of electromagnetic waves. The subsidiary aim of the course is to provide an account of the electrical and magnetic properties of materials.
The main aim of the optics part of the course is to understand Fraunhofer and Fresnel diffraction, and to introduce laser physics.
