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?
