Light crosses empty space at three hundred million metres a second and travels in straight lines. Follow one of those lines into a mirror, a block of glass, a pinhole, an eye and a prism.

- 01Light travelsModelA flash and a bang leave the same hillside at the same instant and arrive six seconds apart. One of them needed air to get to you. The other did not need anything.Open this lesson
- 02Reflection: mirrors and scatteringModelA mirror and a sheet of paper obey exactly the same rule when light lands on them. Only one of them shows you your face, and the reason is the surface rather than the rule.Open this lesson
- 03RefractionProcessA straw stood in a glass of water looks snapped at the surface. What is really going on?Open this lesson
