This applet shown the diffraction/interference for multiplt slits.
Drag the N slider bar to change the number of slits from 1-20. (1 for single slit)
Other slider bars at the bottom allow you to change the Slit width, Slit separation and Wavelength of the light source.
Slider bar on the top change the spatial resolution in the horizontal direction.
Slider bar at the right change the ntensity of the light source.
uncheck the checkbox to remove intensity plot (only display spectrum on the screen).

You should be able to find VIEW and DOWNLOAD links just below the EJS simulation to view/download the EJS source.
You should be able to open the ejs source if you downloaded the EJS jar file and also have installed EJS.
Double click the jar file to run it, right click in the simulation region and select open EJS model, and the source will be opened in EJS.

You might want to check out http://physci.kennesaw.edu/mzoughi/Simulations.shtm for several similar simulations.
