Question 7 of10 In the two-slit interference experiment of the gure, the slit widths are each 13.1 um. their separation is 26.2 pm, the wavelength is 624 nmI and the viewing screen is at a distance of 4.23 m. Let ip represent the intensityIr at point Pon the screen, at height y= T23 cm. [a] What is the ratio of lp to the intensityIr im at the center of the pattern? Determine where P is in the two-slit interference pattern by giving the order number of the {b} maximum and [c] minimum between which it lies. Next, for the diffraction that occurs. determine where point P is in the diffraction pattern by giving the order number of the [d] minimum and (e) next minimum (larger) between which it lies. [a] Number (b) Number [c] Number (d) Number [e] Number Incident wave Path length difference AL ((1) Waves from slits 51 and Sz(which extend into and out of the page) combine at P, an arbitrary point on screen C at distance y from the central axis. The angle 6 serves as a convenient locator for P. (b) For B 3' d, we can approximate rays r1 and r; as being parallel, at angle 3 to the central axis.
