- A laser beam (λ=497 nm) is put through a beam splitter to give 2 equal intensity beams traveling parallel to one another. One of these beams is directed through a double slit apparatus, and the other beam through a single slit apparatus. The single slit and the double slits are in the same plane and both display fringe patterns on a screen a distance L= 3.3 m away. a. The slit spacing of the double slit apparatus is 0.63 mm. What is the distance from the center of the double slit fringe pattern to the 5th dark fringe? b. If the third dark fringe of the single slit pattern is the same distance from the center of the single slit pattern as the result for part (a), what is the single slit width? To continue, please enter the result of part b) in mm.
