283335 In Young's double slit experiment, the separation \(d\) between the slits is \(2 \mathrm{~mm}\), the wavelength \(\lambda\) of the light used is \(5896 \AA\) and distance \(D\) between the screen and slits is 100 \(\mathrm{cm}\). It is found that the angular width of the fringes is \(0.20^{\circ}\). To increase the fringe angular width to \(0.21^{\circ}\) (with same \(\lambda\) and \(D\) ) the separation between the slits needs to be changed to
283338 Interference fringes were produced in Young's double slit experiment using light of wavelength \(6000 \AA\). When a transparent film of thickness \(3 \times 10^{-3} \mathrm{~cm}\) was paced over one of the slits, the fringe pattern is shifted by a distance equal to 20 fringe widths. The refractive index of the material of the film is
