1. Two slits in Young's double slit experiment are 1.5 mm apart and the screen is placed at a distance of 1m from the slits. If the wavelength of light used is \(600 × 10^{−9}\,m\) then the fringe separation is
(1). \(4 × 10^{−5} m\)
(2). \(9 × 10^{−8} m\)
(3). \(4 × 10^{−7} m\)
(4). \(4 × 10^{−4} m\)
