Education
A live, numerically-simulated wave tank where you place sources and barriers and watch real interference and diffraction patterns emerge. Two coherent sources produce the classic fringe pattern; a barrier with one or two slits shows genuine single- and double-slit diffraction, with an intensity readout along a "screen" so you can see the fringes as a proper measured curve. This isn't a canned animation — it's an actual finite-difference wave-equation solver, so unusual source and obstacle setups produce genuinely correct results.
