Light and Optics: an interactive 3D physics chapter

Light and Optics, an interactive 3D physics chapter for GCSE and Cambridge IGCSE students, with one A-level topic, interference. Ten lessons on a carousel slide projector: each slide’s drawing steps off the wall into the projector’s beam. Each lesson teaches one idea step by step at your own pace, lets you try the experiment yourself, then asks a quiz question about a new situation.
