Diffraction on a thin wire.A thin wire is placed in a beam produced by either a Helium-Neon laser operating at 632.8 nm (red,bottom panel) or a Helium-Neon laser operating at 543.4 nm (green,top panel). The resulting diffraction patterns are observed at the same distance from the wire. Note that the fringe spacing is smaller for the green laser. Also note a bright line at the center of the geometric shadow | |
