Laser light with wavelength 620 nm from a laser passes through a single slit that is 0.370 mm wide. The diffraction pattern is observed on a screen that is 2.65 m away. Calculate the width (in mm) of the first bright fringe that is directly beside the central bright fringe. Round your answer to 2 decimal places. Laser light with wavelength 568 nm is incident on a double slit and produces an interference pattern 1.90 m away. The distance between any two dark fringes in the pattern is 4.35 mm. Calculate the separation (in mm) of the two slits. Round your answer to 3 decimal places.
