Almas shines light of wavelength 453 nm through two slits. In the interference pattern on a screen 2.6 m away, adjacent bright fringes are separated by 6.9 mm in the general vicinity of the center of the pattern. What is the separation of the two slits in millimeters? Please give your answer with three decimal places.
