An interference pattern is produced by light of wavelength 580 nm from a distant source incident on two identical parallel slits separated by a distance (between centers) of 0.530 mm.
(a) If the slits are very narrow, what would be the angular positions of the first-order and second-order, two-slit, interference rnaxima?
(b) Let the slits have width 0.320 mm. In terms of the intensity 10 at the center of the central maximum, what is the intensity at each of the angular positions in part (a)?
