In a two-slit Young's interference experiment, the aperture-to-screen distance is 2 m and wavelength of a monochromatic light is 600 nm. Ask: a) If it is desired to have a fringe spacing of 1 mm, what is the required slit separation? b) If a thin film plate with a refractive index (n 1.6) and thickness (t 0.05 mm) is placed over one slit, what is the resulting lateral fringe displacement at the screen?
