What is the effect on Fresnel's biprism experiment when the use of white light is made?

In a Fresnel's biprism experiment, sodium light of wavelength 5832 Å is used. Calculated the fringe width, given the distance between the screen and the biprism =120 cm and the distance the two sources=0.04 cm.

In Fresnel’s biprism experiment if the screen is moved away from the biprism, then the fringe width will :

In fresnel's biprism experiment the distance between the source and the screen is 1 ma nd that between the screen is 1 m and that between the source and biprism is 10 cm. the wavelength of light used is 6000Å. The fringe width obtained is 0.03 cm and the refracting angle of biprism is 1^(@) then calculate the refractive index of the material of biprism.

In Fresnel's experiment, the width of the fringe depends upon the distance
