Java based diffraction simulation. Diffraction and Interference Model: Single and Double Slits shows diffraction and interference patterns from a single slit, double sources and double slits. The user can change the source wavelength, slit width, separation and distance between slit and screen.

With this simulation, you can explore the ideas of interference and diffraction resulting from waves passing through a single opening (the single slit); waves being emitted with equal amplitude in all directions from two sources (the double source), and waves passing through two closely spaced openings (the double slit). Note that the double-slit pattern is a combination of the single-slit and double-source patterns.
