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.

Fringes are produced with monochromatic light of wavelength 5500 Å. A thin glass plate of R.I. 1.5 is then placed normally in one of the paths of interfering beams and the central bright fringe is found to be shifted to the position, previously occupied by the third bright band from the centre. the thickness of the glass plate is

Fringes are produced with monochromatic light of wave-length 5.45xx10^(-5) cm. A thin glass plate of refractive index 1.5 is then placed normally in the path of one of the interference beams and the central bright band of the fringe system is found to move into the position previously occupied by the third bright band from the system. Find the thickness of the glass plate.

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.

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.

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 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?

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 YDSE a thin film (mu=1.6) of thickness 0.01 mu m is introduced in the path of one of the two interfering beams. The central fringe moves to a position occupied by the 10th bright fring earlier. The wave length of wave is
