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

What is a model?
State the wave equation and use it to find the wavelength of light with a frequency of 10.2 x 1010 Hz
What part of the EM spectrum does this light represent
Explore and elaborate
Practical: Properties of waves
