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

What part of the EM spectrum does this light represent?
Watch this experiment of light polarisation
