Description
This simulation will allow students to gain a better understanding of quantum wave interference as they watch waves of different types of particles spread out and interfere as they pass through a double slit. Students will use quantum detectors to explore how measurements change the waves and the patterns they produce on the screen.
Using the simulation, students will:
- 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.
