Young's double slit experiment is conducted with monochromatic light of wavelength 5000\(\mathop A\limits^o\), with slit separation of 3 mm and observer at 20 cm away from the slits. If a 1 mm transparent plate is placed infront of one of the slits, the fringes shift by 6 mm . The refractive index of the transparent plate is
