2 In Young s double slit experiment the separation d between the slits is 2 mm the wavelength of the light used is 5896 and distance D between the screen and slits is 100 cm It is found that the angular width of the fringes is 0 20 To increase the fringe angular width to 0 21 with same and D the separation between the slits needs to be changed to 1 1 8mm R 2 17mm f 2 1 9mm
