A monchromatic beam of electrons accelerated by a potential difference V falls normally on the plate containing two narrow slits seperated by a distance d. The interference pattern is observed on a screen parallel to the plane of the slit and at a distance of D from slits. Fringe width is found to be `omega_(1)`. When electron beam is accelerated by the potential differene of 4V, the finge width becomes `omega_(2)`. Find the ratio `(omega_(1))/(omega_(2))`. (Given `dltltD`)

Answer
