Quality control systems have been developed to remotely measure the diameter of wires using diffraction. A wire with a stated diameter of 170 μmblocks the beam of a 633 nm laser, producing a diffraction pattern on a screen 50.0 cm distant. The width of the central maximum is measured to be 3.77 mm.

A) What is the diameter of the wire? a = ___ (value) ___ (units)

B) The wire should have a diameter precisely within 1% of the stated value. Does this wire pass the test? YES or NO

Thanks!!

    Investigators measure the size of fog droplets using the diffraction of light. A camera records the diffraction pattern on a screen as the droplets pass in front of a laser, and a measurement of the size of the central maximum gives the droplet size. In one test, a 690 nm laser creates a pattern on a screen 30 cm from the droplets. Part A If the central maximum of the pattern is 0.32 cm in diameter, how large is the...

    Diffraction can be used to provide a quick test of the size of red blood cells. Blood is smeared onto a slide, and a laser shines through the slide. The size of the cells is very consistent, so the multiple diffraction patterns overlap and produce an overall pattern that is similar to what a single cell would produce. Ideally, the diameter of a red blood cell should be between 7.5 and 8.0 μm. If a 633 nm laser shines through...

    Manufacturers of wire (and other objects of small dimensions) 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 (see Fig. 37-50). Suppose a laser of wavelength 648.2 nm, illuminates a wire, and the diffraction pattern appears on a screen 2.52 m away (do not use the number shown in the diagram). If the...
