In Young’s double slit experiment the separation d between the slits is 2mm, the wavelength λ of light used is 5896 A and distance D between the screen and slits is 100 cm. It is found that the angular width of the fringes is 0.20 degree. To increase the fringe angular width to 0.21 degree (with same λ and D) the separation between the slits needs to be changed to
