Diffraction on an aperture,Photo 1 of 2..A round aperture is placed in a beam produced by either a Helium-Neon laser operating at 632.8 nm (red,Photo 1) or a Helium-Neon laser operating at 543.4 nm (green,Photo 2). The resulting diffraction patterns are observed at the same distance from the aperture. Note that the fringe spacing is smaller for the green laser | |
