The change in diffraction pattern of a single slit, when the monochromatic source of light is replaced by a source of white light will be

When a source of white light is used instead of a monochromatic source, the diffracted image of the slit gets dispersed into constituent colours of white light. The central maximum will be white and on either side of the central maximum, there will be coloured fringes. As fringes of other colours fall at different places we see fringes of all colour on the central bright fringe.
