Unformatted text preview: interferometer with a lens inserted in one of the two arms? 1 1000 2000 spherical wave k x z Figure B 3. Repeat the calculations of the previous problem for the case when the plane wave is propagating oaxis as shown in Figure C below. Explain the dierences that you observe. o 1 1000 2000 x z spherical wave 30 k Figure C 4. A fan of N plane waves are propagating symmetrically with respect to the z axis, as shown in gure D below. The angular spacing between successive members of the fan is xed and equal to . Describe the interference pattern observed on a plane perpendicular to the z axis. 2 z n= n=N 1 x Figure D 5. Describe the interference pattern between two counterpropagating plane waves. This is also known as a standing wave. Explain why. 3 MIT OpenCourseWare http://ocw.mit.edu 2.71 / 2.710 Optics Spring 2009 For information about citing these materials or our Terms of Use, visit: http://ocw.mit.edu/terms ....
