In a double-slit experiment, the slit separation is 0.160 mm and the width of each slit is 0.020 mm. The slits are illuminated at normal incidence with light of wavelength 600 nm and the resulting interference pattern is viewed on a screen located 2.00 m from the plane of the slits. (a) How many bright fringes are there in the central diffraction maximum? figure where (b) The intensity of the light is measured at a point where X = 72.25 cm from the central fire out maximum measured along the screen. What is the ratio of the intensity at this point to the intensity of the central maximum? (c) Draw the diagram showing the intensity as a function of the position.
