The 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.

The Diffraction and Interference Model was created using the Easy Java Simulations (EJS) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the ejs_bu_Diffraction_Interference.jar file will run the program if Java is installed.

Please note that this resource requires at least version 1.5 of Java (JRE).

in another computer i can see the error message on the ejs console. hope it helps in the debugging of EJS_4.3.7_130516\EJS_4.3.7.

thanks!
