1. Laser beam with wavelength 632.8 nm is aimed perpendicularly at opaque screen with two identical slits on it, positioned horizontally, and close enough to each other so that both of them fall in the beam. A precise positioning shield is used to cover alternatively one of the slits, while the other remains open. On an observation screen positioned 1 meter further from the opaque screen, the diffraction patterns from the independent slit illumination were found identical, with minima 4.0...

A 600 nm laser shines through a double slit in which the two slits are 0.8 mm apart, and each slit is 0.1 mm wide. Sketch what the pattern would look like on a screen 3 m away and indicate the central maximum. How many bright spots lie between the first single-slit minimums on either side? How far away is that first single-slit minimum from the center of the pattern? (you may assume the small angle approximations)
