In a two slit experiment with monochromatic light fringes are obtained on a screen placed at some distance from the sits. If the screen is moved by \[5\times {{10}^{-2}}\]m towards the slits, the change in fringe width is \[3\times {{10}^{-5}}\]m. If separation between the slits is \[{{10}^{-3}}\] m, find the wavelength (in\[\overset{\text{o}}{\mathop{\text{A}}}\,\]) of light.
