In a Young's experiment, the upper slit is covered by a thin glass plate of refractive index `1.4` while the lower slit is covered by another glass plate having the same thickness as the first ont but having refractive index `1.7.` Interference pattern is observed using light of wavelength `5400 A.` It is found that the point `P` on the screen where the central maximum fell berore the glass were inserted now has `(3//4)^(th)` the original intensity. It is further observed that what used to be the `5th` maximum earlier, Iies below the point `O` while the `6th` minimum lies above `O.` The thickness of the glass plate in `nxx10^(-7)m.` Find the value of `n`
(Absorption of light by glass plate may by neglected)
