PHYS 352, Spring 2013 Fraunhofer diffraction maxima. A monochromatic beam (=643 nm) passes through an aperture of width 2.5 m. Solve for the first several angles, m, of the diffraction maxima in the Fraunhofer limit two different ways: a. By graphical analysis of a transcendental equation in , where =0.5kbsin(). The aperture width is b. The wave number is k. b. By iteration. You might choose to use Newton’s method. Start the iterations with values near, but not equal to, your answers from part a. Newton’s method only converges when the starting point is close to the final answer. Feel free to use a more sophisticated numerical iteration technique if you wish.
