50 : In a biprism experiment the eye-piece kept at a distance of 1.5 m from the slit. The distance of second dark band from the central point was found to be 1.2 mm. The sizes of magnified and diminished images of the slits produced by the convex lens are found to be 2.4 mm and 0.6 mm and 0.6 mm respectively. Calculate the wavelength of light used.
