Slit Experiment SHOWCASE

What you are seeing: a source, an N-slit mask, and a screen, viewed through four interchangeable modes (Wave field, Particle accumulator, Grating, Davisson-Germer). The Fraunhofer formula I(θ)=(sin⁡α/α)2(sin⁡Nβ/sin⁡β)2I(\theta) = (\sin\alpha/\alpha)^2 (\sin N\beta/\sin\beta)^2 governs every mode

Figure 1. Slit Experiment legend: source, N-slit mask, screen, with wave/particle/grating/Davisson-Germer modes. Method: closed-form Fraunhofer (sin alpha / alpha)^2 (sin N beta / sin beta)^2 + rejection-sampled particle hits.

WHAT TO TRY

  • Vary each control and watch the rail readouts respond.
  • Compare the diagnostic plot against the live scene.
