Unformatted text preview: question you can use the applet at: http://physics.neiu.edu/vpl/optics/diffraction.html. For the applet, set the slit width to 0.1 (small enough that the slits are approximately point sources) and wavelength to 10. (d) A CCD camera is placed 1 m away from the slits. The pixel size is 20 microns, what is the wavelength resolution of this CCD+slit spectrometer if the fringes were infinitely sharp? Again assume a slit separation of d = 50µm and that the 10 µm fringe is at the middle of the CCD. 2 6.007 Spring 2011 Problem Set 7 Problem 7.3 Plane waves from the same source can form an interference pattern (subject to some conditions we’ll ignore here). In practice that means that when waves reflect from boundaries a standing wave pattern can be formed on the side of the boundary containing the incident and reflected waves. The figures on the next page indicate the standing wave patterns resulting when an incident wave in medium 1 with amplitude equal to 1 V/m is incident on an interface. Label the graphs (a)-(d) to match them with the description detailed below. Note that not all figures have a description (10 figures, 4 descriptions). x Medium 1 Medium 2 z Image by MIT OpenCourseWare. (a) Plot of |Ey,total | with medium 1 being air, medium 2 n2 = 2.

The basic idea is to split a beam of light into two beams (which are initially in phase), and send each through an identical path length, and then...
