An investigator finds a fiber at a crime scene that he wishes to use as evidence against a suspect. He gives the fiber to a technician to test the properties of the fiber. To measure the diameter of the fiber, the technician places it between two flat glass plates at their ends as in the figure below. When the plates, of length 13.8 cm, are illuminated from above with light of wavelength 670 nm, she observes bright interference bands separated by 0.540 mm. What is the diameter of the fiber?
