Fringes are obtained with the help of a biprism in the focal plane of an eyepiece distant 1 m from the slits. A convex lens produces images of the lit in two position between biprism and eyepiece. The distances between two images of the slit in two position are `4.05xx10^(-3)m` and `2.9xx10^(-3)m` respectively. Calculate the distance between the slits.
