(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 maximu and minimum intensity of the fringe in the interference pattern.
(b) What kind of fringes do you expect to observe if white light is used instead of monochromatic light ?
