In an interference experiment of the Young type, the distance between slits is 0.5 mm and the wavelength of the light is 600 nm. (a) If it is desired to have a fringe spacing of 1 mm at the screen, what is the proper screen distance? (b) If a thin plate of glass (n= 1.50) of thickness 100 microns is placed over one of the slits, what is the lateral fringe displacement at the screen? (Note: This is the same as asking where the center peak is shifted to in terms of number of periods.) (c) What path difference corresponds to a shift in the fringe pattern from a peak maximum to the (same) peak half-maximum?
