About This Lesson
When do photons, electrons, and atoms behave like particles and when do they behave like waves? Watch waves spread out and interfere as they pass through a double slit, then get detected on a screen as tiny dots. Use quantum detectors to explore how measurements change the waves and the patterns they produce on the screen.
PhET resources are great, this one means that you don't need to struggle with a laser to show double slit interference and you can also show other types of particles. Very useful as a demonstration.
