About this topic
In this series of eight lessons, learners will be introduced to the properties of light, namely reflection and
refraction. The learners will gain an understanding into the dual nature of light – that it is both a wave and a
particle. They will then explore reflection and refraction in detail and learn where they are used in everyday life.
