The double-slit experiment is a great practical activity for explaining the complex laws of physics.
A single photon will visit both slits at the same time when passing through double slits, before combining to create one single wave.
Use this in the classroom to explain the pros and cons of the different models of light.
Ross Spearing, Head of Astronomy and STEM co-ordinator at Devonport High School for Boys, shared this idea after hearing Professor Roy Samble's lecture Models for light: Wave-particle duality at our Communicating Complex Physics CPD day.
Schools Programme members can download the resources from the event in the PTI Staffroom.
