In Young' s experiment, the source is of red light of wavelength `7X10^(-7)m` .When a thin glass plate of refractive index `1.5` at this wavelength 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 `5^(th)` bright fringe. Find the thickness (in `mu m` ) 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?

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?

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.

In a YDSE, fringes are produced by monochromatic light of wavelength 5450Å. A thin plate of glass of refractive index 1.5 is placed normally in the path of one of the intefering beams and the central bright band of the fringe system is found to move into the position previoysly occupied by the third band from the centre. select the correct alternatie

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.

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

In a young 's double slit experiment, a glass plate of refractive index 1.5 and thickness 5 times 10^-4 cm is kept in the path of one of the light rays. Then

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 )

A double slit experiment is performed with light of wavelength 500nm . A thin film of thickness 2mum and refractive index 1.5 is introduced in the path of the upper beam. The location of the central maximum will
