    In a biprism experiment, a steady interference pattern is observed on the screen kept at a distance of 100 cm using a light of wavelength 5000 A˚5000\ \mathrm{\mathring{A}}. Without changing the distance between the virtual images of the slit, the source of light is replaced by a source of wavelength 6400 A˚6400\ \mathrm{\mathring{A}}. Now, to reduce the fringe width by 20%20\% of its initial value, the screen should be moved
