SlitTwo Dringe

What is it about?

SlitTwoDringe is a handy toolkit for planning and checking particle-and-wave experiments. Switch between kinetic energy and momentum fast to match your beam settings. See when quantum effects show up by estimating a particle’s thermal wavelength. Predict two-slit fringe spacing and diffraction angles to place slits, screens, and gratings with confidence. Get an electron’s wavelength from the applied voltage, or find the momentum for a target wavelength. Work out how close the speed is to light and the simple “gamma” number used at high speeds. Estimate the focus of a basic magnetic lens to guide electron-microscope setup. Size wavepackets with a quick Δx–Δp check, and use the right wavelength for very fast particles.
