Question

In a two slit experiment with monochromatic light fringes are obtained on a screen placed at some distance from the slits. If the screen is moved by $5 	imes {10^{ - 2}}\,m$ towards the slits, the change in fringe width is $3 	imes {10^{ - 5}}\,m$. If separation between the slits is ${10^{ - 3}}\,m$ the wavelength of light used is
