3 Example: Double-Slit Diffraction (Ch. 36 # 41) In the double-slit interference experiment the slit widths are each 13.9 pm, their separation is 27.8 um, the wavelength is 642 nm, and the viewing screen is at a distance of 4.16 m. Let Ip represent the intensity at point P on the screen, at height y = 72.5 cm. a) What is the ratio of 1, to the intensity Im at the center of the pattern? b) Determine where P is in the two-slit interference pattern by giving the order number of the maximum and minimum between which it lies. c) Determine where point P is in the diffraction pattern by giving the order number of the (d) minimum and (e) next larger minimum between which it lies.
