Diffraction experiment. Simulation showing the variation in the interference pattern produced by light waves passing through a multi-slit aperture. N is the number of slits and D is the distance between slits in micrometres. The wavelength of the light is 633 nanometres. The diffraction causes the light waves to overlap, causing constructive and destructive interference. The intensity of the light (red) is shown on a diffusing screen, and as a curve (white). N varies from 2 to 4 to 16 (top to bottom) and D varies from 1 to 2.5 to 7 from left to right. As N increases, the interference maxima become sharper. As D increases, the maxima converge.
