“(a) If one of two identical slits producing interference in Young's experiment is covered with glass, so that the light intensity passing through it is reduced to 50%, find the ratio of the maximum and minimum intensity of the fringe in the interference pattern. (b) What king of fringes do you expect to observe if white light is used instead of monochromatic light?”
MY DOUBT IS: In the first part of the question, won't introducing a glass sheet will make the slits non-coherent? If so will there be sustained interference?
