Light of wavelength 585 nm falls on a slit 0.0655 mm wide.
Part A On a very large distant screen, how many totally dark fringes (indicating complete cancellation) will there be, including both sides of the central bright spot? Solve this problem without calculating all the angles! (Hint: What is the largest that sin theta can be? What does this tell you is the largest that m can be?)
Part B At what angle will the dark fringe that is most distant from the central bright fringe occur?
