Problem 9 You shine your favorite laser pointer (which has a wavelength of 450 nm) towards two slits adistance d apart. You then observes the second order (m=2) bright fringe to be 5.0 cm away from the centralbright maximum on a screen 4.0 meters away. You now shine your second favorite laser pointer (which hasa wavelength of 530nm) onto the slits, how far away from the central bright maximum will the third order(m=3) bright fringe be located? Part 1: Double-Slit InterferenceIn lecture you studied Thomas Young's classic double-slit experiment. A basic analysis of this experiment follows. Whenmonochromatic and coherent (i.e. in-phase) light is incident on a pair of slits, the transmitted light appears as two separatesources that propagate, in-phase, to a distant screen. The resulting pattern on the screen (Figure 1) consists of a seriesof bright and dark stripes called "interference" fringes. The fringes result from the different path lengths taken by the twoseparate waves. For an “in-phase" condition to exist (bright stripe on the screen; "constructive interference"), the path lengthdifference AL must be an integer number of wavelengths, mλ. Conversely, if the path length difference for the two waves isexactly m(), the waves will effectively cancel each other at the screen ("destructive interference"), forming a dark stripe.The exact fringe pattern observed on a fixed screen depends on both the wavelength of incident light and the double-slitspacing.Incoming LightALDFigure 1: Geometric construction of Young's Double-Slit Experiment.1
