Module 4: Electrons Waves and Photons

The aim of this module is to ultimately introduce key ideas of quantum physics.

Electromagnetic waves (e.g. light) have a dual nature. They exhibit both wave and particle-like behaviour. The wave–particle dual nature is also found to be a characteristic of all particles (e.g. electrons).

Before any work can be done on quantum physics, you need to appreciate what electrons are and how they behave in electrical circuits. A basic understanding of wave properties is also required.

In this module, you will learn about electrons, electric current, electrical circuits, wave properties, electromagnetic waves and, of course, quantum physics.
