When one of the slits of Young's experiment is covered with a transparent sheet of thickness 4.8 mm, the central fringe shifts to a position origially occupied by the `30^(th)` the central fringe has to shift to the position occupied by `20^(th)` bright fringe?

When one of the slits of Young's experiment is covered with a transparent sheet of thickness 4.8mm , the central fringe shifts to a position originally occupied by the 30th bright fringe. What should be the thickness of the sheet if the central fringe has to shift to the position occupied by 20th bright fringe?

In a Young's experiment, one of the slits is covered with a transparent sheet of thickness 3.6xx10^(-3)cm due to which position of central fringe shifts to a position originally occupied by 30th fringe. If lambda=6000 Å , then find the refractive index of the sheet.

In a Young's experiment, one of the slits is covered with a transparent sheet of thickness 3.6xx10^(-3)cm due to which position of central fringe shifts to a position originally occupied by 30th fringe. If lambda=6000 Å , then find the refractive index of the sheet.

A thin sheet of a transparent material (mu= 1.60) is placed in the path of one of the interfering beams in a YDSE using sodium light, lambda= 5890 dotA . The central fringe shifts to a position originally occupied by the 12th bright fringe. Calculate the thickness of the sheet.

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 center. find the thickness of the glass plates.

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. If the source is now changed to green light of wavelength 10^(-7)m , the central fringe shifts to a position initially occupied by the sixth bright fringe due to red ligth. What will be refractive index of glass plate for the second ligth for changed source of ligth?

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 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 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?
