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
