3b. Consider the interference pattern produced by two slits of width a and separated by a distance d, whered = 3a. The slits are illuminated by normally incident light with wavelength one fifth the slit separation(Lambda=d/5).

(b) Now let's include diffraction effects caused by the slit width. At what angles would you expect to see slit diffraction minima? You should conclude that some of the 2-source interference maxima are \"missing\"that is, they have intensity of zero. Which are missing
