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

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?

A beam of light consisting of two wavelengths 6500 A ˙ and 5200 A ˙ is used to obtain fringes in a Young's double slit experiment.Find the distance of the third bright fringe on the screen from central maximum for the wavelength 6500 A. The distance between the slits is 2mm and the distance between the plane of the slits and the screen is 120 cm

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?
