Quantum Wave Interference
This simulation has not been translated into this language. You can still access the English version below.
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.

Sample Learning Goals
- Visualize a photon, electron, neutron, or helium atom as a wave packet that collapses upon detection.
- Visualize what happens to the wave between slit and screen.
- Justify how the double slit experiment explains that matter and light behave as waves.
- Describe the behavior of a wave function in the presence of a detector, and explain how putting a detector over a slit destroys the interference pattern. Determine how the interference pattern will change if you change the mass, speed, or wavelength.
- Recognize large range of size scales involved in quantum interference experiments.
- Recognize that two coherent light sources can interfere, but only if they have the same wavelength.
