9 A monochromatic beam of electrons accelerated by a potential difference V falls normally on the plate containing two narrow slits separated by a distance d The interference pattern is observed on a screen parallel to the plane of the slits and at a distance of D from slits Fringe width is found to be When electron beam is accelerated by the potential difference of 4V the fringe width becomes 2 Find the ratio 1 Given d D 2
