6 In a biprism experiment the distance between the slit and focal plane of eyepiece is 1. Wavelength of light used is 6000 Å. When a convex lens is interposed between biprism and eyepiece the distance between images of the two virtual sources given by the lens in two different positions are 3.6 mm and 2.5 respectively. Calculate the fringe width.
