When a thin sheet of a transparent material of thinkness `7.2xx10^(-4)`cm is introduced in the path one of the interfering beams, the central fringe shift to a position occupied by the sixth bright fringe. If `lambda=6xx10^(-5)` cm, find the refractive index of the sheet.

A thin sheet of glass (mu=1.520) is introduced normally in the path of one of the two interfering waves. The central bright fringe is observed to shift to position originally occupied by the fifth bright fringe. If lambda=5890Å . Find the thickness of the glass 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.

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.

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 orginally occupied by 30th fringe. If lambda=6000 Å , then find the refractive index of the sheet.
