    Not entirely sure...but is it the stuff with light interference?? If it is...cos white light has many different wavelengths of light...each diffracts through slits by different amounts, so each wavelength's of light's interference patterns are superimposed on top of one another.

    Make sense?

    not really,but thanks for telling me.
    the answer is there will be a white central maximum, and then there will be a spectrum from red through to violet on either side of the central maximum,which doesnt make any sense to me.
