shown knowledge of

1. the wavelengths of visible light and the fact that visible light can be split by a prism

2. the ways in which light can be reflected, refracted and dispersed

demonstrated the ability to

3. use the law of reflection to make calculations on smooth surfaces on at least two occasions

4. use the law of reflection to make calculations on rough surfaces on at least two occasions

5. use Snell’s Law (the law of refraction) to make calculations on at least two occasions

6. explain the optical dispersion of light through a prism with a labelled drawing

7. use the laws of reflection, refraction and/or dispersion to explain the phenomenon of rainbows, halos or mirages.
