The Double Slit Wave-Particle Duality Model demonstrates how matter and light display both wave- and particle-like properties in single and double slit experiments. The simulation shows a detector screen placed behind an aperture with one or two open slits. Particles (electrons or photons) pass through the experiment one at a time and their impact is recorded on the screen. Although it is at first difficult to discern a pattern, a diffraction (interference) pattern eventually emerges suggesting that each particle is interfering with itself. The particle seems be going through both slits as if it were a wave but is detected (observed) at only one location as if were a particle. The particle is interfering with itself as if it were simultaneously passing through both slits.
The Double Slit Wave-Particle Duality Model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double click the ejs_qm_DoubleSlitWaveParticleDuality.jar file to run the program if Java is installed.

changes made: flip the detection over time to the right panel instead of the original center panel draw the world view in the center panel added the aperture with slits with left and right added the trail of electron or photon travelling from source gun of electron or photon to screen made the control panel to suit my usual design enjoy!
