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.

A thin glass plate of thickness t and refractive index mu is between screen &one of the slits in young's experiment.if the intensity at the center of the screen is I ,was the intenstity at the same point prior to the introduction of the sheet. (b) One slit of a young's experiment is covered by a glass plate (mu_(1)=1.4) and the other by another glass plate (mu_(2)=1.7) of the same thickness. The point of central maxima of the screen,before the plates were introduced is now occupied by the third bright fringe.Find the thicknes of the thickness of the plates.the wavelength of light used in 4000Å .

In YDSE, the sources is red ligth of wavelength 7 xx 10^(-7) m . When a thin glass plate of refractive index 1.5 is put in the path of one of the interfering beams, the central bright fringe shifts by 10^(-3) m to the position previously occupied by the 5th bright fringe. What is the thickness of the plate?

In a double-slit experiment, fringes are produced using light of wavelength 4800A^(@) . One slit is covered by a thin plate of glass of refractive index 1.4 and the other slit by another plate of glass of same thickness and of refractive index 1.7. On doing so, the central bright fringe shifts to a position originally occupied by the fifth bright fringe from the centre. find the thickness of the glass plates.

In a double-slit experiment, fringes are produced using light of wavelength 4800A^(@) . One slit is covered by a thin plate of glass of refractive index 1.4 and the other slit by another plate of glass of double thickness and of refractive index 1.7. On doing so, the central bright fringe shifts to a position originally occupied by the fifth bright fringe from the centre. find the thickness of the glass plates.

In double slit experiment fringes are obtained using light of wavelength 4800 Å One slit is covered with a thin glass film of refractive index. 1.4 and another slit is covered by a film of same thickness but refractive index 1.7 . By doing so, the central fringe is shifted to fifth bright fringe in the original pattern. The thickness of glass film is

A thin glass plate of refractive index 1.5 is introduced in the path of one of the interfering beam. As a result, the central bright fringe moves to a position previously occupied by the fifth bright fringe. If the wavelength of beam is 6.2 xx 10^(-5) cm , calculate the thickness of glass plate.

A thin plastic of refractive index 1.6 is used to cover one of the slits of a double slit arrangement. The central point omn the screen is now occupied by what would have been the 7th bright fringe before the plastic was used. If the wavelength of light is 600 nm, what is the thickness ( in mu m ) of the plastic?
