The diffraction pattern shown here was generated by placing a diffraction grating with a series of slits spaced 100 µm apart in the path of a beam of sodium molecules. Showing their wave-like nature, the molecules are diffracted from the slits similarly to the laser light in Figure 11. The circles on the plot show the number of molecules detected at different distances from the center of the beam. The solid line is a fit matching theory to the experimental data. (Unit: 5)
