Interference fringes were produced by Young's double slit method, the wavelength of light used being 6000Å. The separation between the two slits is 2 mm.The distance between the slits and screen is 10 cm. When a transparent plate of thickness 0.5 mm is placed over one of the slits. the fringe pattern is displaced by 5 min. Find the refractive index of the material of the plate.
