Manufacturers of wire (and other objects of small dimension) sometimes use a laser to continually monitor the thickness of the product. The wire intercepts the laser beam, producing a diffraction pattern like that of a single slit of the same width as the wire diameter. Suppose a laser, of wavelength 646.3 nm, illuminates a wire, and the diffraction pattern appears on a screen 2.5 m away. If the desired wire diameter is 1.47 mm, what is the observed distance between the two tenth-order minima (one on each side of the central maximum)?
