Outcomes
- Pupils understand that light travels at different speeds in different media.
- Pupils understand that the changing speed of light leads to the pheonmenon of refraction.
Specification References
- 3.14 recall that light waves are transverse waves which can be reflected, refracted and diffracted
- Diffraction is SA only
Starter
- Ask pupils to estimate their top speeds on land and in water.
