Wave Optics

In Young's double slit experiment, the distance between the slits and the screen is \(1.2 \mathrm{~m}\) and the distance between the two slits is \(2.4 \mathrm{~mm}\). If a thin transparent mica sheet of thickness \(1 \mu \mathrm{m}\) and RI 1.5 is introduced between one of the interfering beams, the shift in the position of central bright fringe is
