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

Thomas Young demonstrated his double slit experiment using a single slit illuminating a double slit. Explain why did he use a single slit rather than directly illuminating double slit with the sunlight. Select one: a. This was done in order to reduce the intensity of light. b. This was done in order to obtain as coherent as possible source of light. c. This was done in order to select a certain wavelength of light. Clear my choice
please reexplain this paragraph two-beam interference with the double exciter:the circular waves generated by the double exciter are super- posed at the points where they meet. The areas with no wave motion indicate cancellation (minima).the minima and maxima are positioned along hyperbolas with the excitation centers as focal points. the relationships given in the section h0rinciples” for the positions of the hyperbolas are confirmed experimentally.The interference patterns are determined by the distance be- tween exciters, and by the wavelength. the number of hyperbo- las increases with the exciter spacing and the wavelength, and the hyperbolas open further.
