Light of intensity I0 that has a wavelength equal to lambda = 480 nm falls normally on three slits. Each slit is 2.00 mu m wide and the center-to-center separation between it and the next slit is 4.00 mu m.
1. Find the angular width of the central intensity maximum of the single-slit diffraction pattern on a distant screen. That is, find the angle between the first intensity minima on either side of the central diffraction maximum.
2. Find the angular position of all visible interference intensity maxima that lie inside the central diffraction maximum.
3. What is the order of the maximum which is the closest to the first single-slit diffraction maximum? What is the intensity of this interference maximum?
