In a Young’s experiment the upper slit is covered by a thin transparent plate of refractive index 1.1 and the lower slit is covered by another thin transparent plate of refractive index 1.9 but of thickness half the thickness of the first one. It is observed that the point O on the screen, where the central maxima fall before the insertion of the plates, now has 3/4th of the original intensity. It is also observed that what used to be the 4th maxima earlier lies below O whereas the 4th minimum is above O. Calculate the thickness (μm) of the upper plate. Take the wavelength of light to be 7200 A°and neglect any absorption of light. Correct answer is '7.885'. Can you explain this answer?

In young’s double slit experiment using monochromatic light the fringe pattern shifts by a certain distance on the screen when a mica sheet of refractive index 1.6 & thickness 1.964 microns is introduced in the path of one of the interfering waves. The mica sheet is then removed & the distance between the slits & the screen is doubled. It is found that the distance between the maxima (or minim
