Light of wavelength 500nm is used to form interference pattern in Young's double slit experiment. A uniform glass plate of refractive index 1.5 and thickness 0.1mm is introduced in the path of one of the interfering beams. The number of fringes which will shift the cross wire due to this is

In the ideal double-slit experiment, when a glass-plate (refractive index 1.5) of thickness t is introduced in the path of one of the interfering beams (wavelength lambda ), the intensity at the position where the central maximum occurred previously remains unchanged. The minimum thickness of the glass-plate is

In Young's double slit experiment a mica plate of refractive index mu is introduced in the path of light coming from one of the slit . If the central bright fringe gets shifted to the point originally occupied by the fourth bright fringe, then the thickness of the mica plate will be (symbols have their usual meaning )

In a Young.s double slit experiment, the fringes are displaced by a distance x when a glass plate of refractive index 1.5 is introduced in the path of one of the beams. When this plate is replaced by another plate of same thickness, the shift of fringes is (3"/"2)x . The refractive index of second plate is

One slit of a double slits experiment is covered by a thin glass plate of refractive index 1.4 and the other by a thin glass plate of refractive index 1.7 .The point on the screen ,where central bright fringe was formed before the introduction of the glass sheets,is now occupied by the 15th bright fringe.Assuming that both the glass plates have same thickness and wavelength of light used in 4800Å ,find the their thickness.

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

In Young's double slit experiment, the fringes are displaced index 1.5 is introduced in the path of one of the beams. When this plate in replaced by another plate of the same thickness, the shift of fringes is (3//2)x . The refractive index of the second plate is
