The distances of a point on the screen from two slits in biprism experiment is `1.8xx10^(5)` m and `1.23xx10^(5)` m if wavelength of light used is 6000 Å then fringe formed at that point is

The disntances of poinnt on the screen from two slits are 1.8xx10^(-5)m and 1.23xx10^(-5)m . If the wavelength of light used is 6000 Å, then the number of bright or dark band formed at that point is

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.
