An interference pattern is produced by light with a wavelength 550 nm from a distant source incident on two identical parallel slits separated by a distance (between centers) of 0.580 mm .

a) If the slits are very narrow, what would be the angular position of the first-order, two-slit, interference maxima? (Solve for theta, in radians)

b) What would be the angular position of the second-order, two-slit, interference maxima in this case? (Solve for theta, in radians)

c) Let the slits have a width 0.310 mm . In terms of the intensity I0 at the center of the central maximum, what is the intensity at the angular position of θ1?

d) What is the intensity at the angular position of θ2?
