What is the effect on the interference fringes in Young's double slit experiment when the monochromatic source is replaced by a source of white light?

Draw the graph of intensity distribution in Young's double-slit experiment.

Yellow light of wavelength 6000Å produces fringes of width 0.8 mm in Young's double slit experiment. What will be the fringe width of the light source if it is replaced by another monochromic source of wavelength 7500Å and sepearation between the slits is doubled?

Describe Young's double slit experiment and determine the conditions for obtaining bright and dark fringes.
