Single Slit Diffraction

Measurements are not to scale.

Choose between experiment and results to view either from the list at the bottom left.

When results are displayed, moving  the mouse near the x-axis shows the alignment of individual phasors and the resultant phasor.

The intensity in the sidebands is exaggerated to make them visible. 

Notice the change of scale on the y axis when the slit width is increased. For a  slit width below a certain value the maximum value of  factional intensity on the y axis is 1 and for those above it it is 0.1.

You can view the experimental arrangement from different perspectives by dragging with the mouse, but I guess this option is best unused. You can also shift the arrangement by double clicking any where in the applet area.
