Interference fringes were produced in Young's double-slit experiment using light of wavelength 5000 Å . When a film of thickness 2.5xx10^(-3) cm was placed in front of one of the slits, the fringe pattern shifted by a distance equal to 20 fringe-widths. The refractive index of the material of the film is

YDSE is conducted using light of wavelength 6000 Å to observe an interference pattern. When a film of some material 3.0xx10^(-3) cm thick was placed over one of the slits, the fringe pattern shifted by a distance equal to 10 fringe widths. What is the refractive index of the material of the film ?

YDSE is conducted using light of wavelength 6000 Å to observe an interference pattern. The slits are 2mm apart. The fringes are observed on a screen 10cm away from the slits. When a film of some material 0.5mm thick was placed over one of the slits, the fringe pattern shifted by a 5mm . What is the refractive index of the material of the film ?
