Designed for the new AQA GCSE 9-1 specification. This lesson builds upon properties of waves and looks at reflection. Students will be taught how to draw ray diagrams and show the reflection of light against a mirror, stating the relationship between the angle of incidence and the angle of reflection. Students will then apply this knowledge by looking at periscopes and drawing the path light rays take.

Support sheets are provided to help with drawing ray diagrams through a periscope.
