In the biprism experiment keeping the experimental set up unchanged, the fringe width

If Fresnel's biprism experiement as held in water in spite of air, then what will be the effect on fringe width?

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 Youngs double slit experiment, to increase the fringe width

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

In Fresnel's biprism experiment, when the distance between the slit aperture and eye is increased, then distance between the fringes

In the Fresnels biprism experiment, the two coherrent sources are obtained by :
