A coherent light With wavelength A = 054 nm illuminates a double slit setup With a slit spaCing ot a = U.U991 mm. l he intenSIty or light is measured along a distant screen at different angles. When one slit is covered the intensity on the screen is IO = 32.1 W/mz. In this problem ignore any effects due to diffraction of light around the slits. \\ / /R\\ Screen Figure 1. Coherent light of wavelength [1 is incident on two slits separated by a distance d with a distant observation screen behind. The point of interest on the observation screen is an angle 6 from the horizontal at the centre of the two slits. The sketch is not scale: the screen distance is >> d. Part 1) At 6 = 0.0234 rad what is the phase difference between the light arriving from the two slits? but: Part 2) What intensity is observed on the screen at this point? 1::wm2 Part 3) What is the maximum intensity observed at any point on the screen? ii ,,.. n
