Fresnel s biprism having an angle 1 and index of refraction

Fresnel s biprism having an angle 1 and index of refraction 1 5 forms interference fringes on a screen placed 80 cms from biprism If the distance between the slit and the biprism is 30 cms find the fringe separation when wavelength of light used is 5000 A Calculate the fringe separation when the distance of 80 cms and 30 cms are interchanges Ans 0 00394 cm
