In a biprism experiment, the distance between the two virtual images of the slit is 1.2 mm and the wavelenght of light used is 4000Å . If the distance of third bright band from central bright band is 1 mm, and the distance is and the distance between the brprism and focal palne of the eyepiece is 0.9 , then distannce between slit and biprism will be
