In a Young's double slit experiment ,a thin sheet of refractive index 1.6 is used to cover one slit while a thin the sheet of refractive index 1.3 is used to cover the second slit.
The thickness of both the sheets are same and the wavelength of light used is 600 nm.
If the central point on the screen in now occupied by what had been the 10th bring fringe (m=10 ) , then the thickness of covering sheets is

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

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?

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.

The figure shows a Young's double slit experimental setup. It is observed that when a thin transparent sheet of thickness t and refractive index mu is put front of one of the slits, the central maximum gets shifted by a distance equal to n fringe widths. If the wavelength of light used is lambda , t will be :

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.

A very thin sheet of plastic having refractive index mu=1.5 covers one slit of a double slit apparatus illuminated by 700 nm light . The central point on the screen , instead of being maximum , is dark . What is the possible thickness of the plastic in (nm) ?
