About
An interactive 3D web application that visualises the quantum double-slit experiment.
Users fire photons or electrons at a barrier with two slits and watch an interference pattern build on a detection screen.
The double-slit experiment sends quantum particles through two narrow openings; when they are not measured at the slits, they behave like waves and produce bright and dark bands on a screen from interference. When which-path information is introduced, the pattern shifts toward two lumped bands—classic evidence of wave–particle duality.
This app’s objective is to make those ideas tangible: explore the bench in three dimensions, scrub time to see hits accumulate, toggle observer-style measurements, and adjust slit geometry and wavelength so the physics is clear for students and teachers.
Key capabilities in the demo:
- Timeline Scrubber — Drag through time to watch particles accumulate dot by dot.
- Observer Toggle — See wave function collapse when observing which slit.
- 360° Orbital Camera — Explore like a physics bench.
- Adjustable Parameters — Slit width, separation, wavelength, emission rate.
