Problem 2:(a) Consider the double-slit experiment in which the slit separation, d, is equal to the slit width, a.Explain how this set up is equivalent to a single-slit experiment with slit width 2a. In particular, whathappens to the interference peaks of that double-slit experiment (besides the central peak)? What happensto the diffraction peaks of that double-slit experiment (besides the central peak)? Sketch the intensitypattern to elucidate the equivalence.(b) To prove that equivalence even further, show that the intensity function of the double-slit experiment[sin(o/2)'(/2)I(0) = Iocos (8/2)(1)reduces to the correct intensity function of the single-slit experiment with slit width 2a. Recall o = 27 a sineand 8 = 27 dsin @%3D(c) Now ignore diffraction. A laser with 600 nanometer wavelength is shines at two slits separated by 2millimeters. An interference pattern forms on a screen 1.5 meters behind the slits. How many maxima areilluminated on the screen? Assume the screen is very large.
