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?
