OUTCOME
By the end of the lesson you will recognise that light is modeled as a wave and the properties of a light wave determine where light appears on the EM-spectrum
Light is a difficult phenomenon to explain. It is modeled as a ray, a particle and a wave. The wave-particle duality of light is used to describe light
LEARNING TASKS
