In an experiment with Fresnel biprism sodium light is used and bands 0.0196 cm in width are observed at the distance of 100 cm from the slit. A convex lens is placed between the biprism and the slit. If the distance between the slit and screen is one meter, the magnified distance apart of the images is found to be 0.7 cms, the lens being 30 cm from the slit, calculate the wavelength of light.
