The young's double slit experiment is done in a medium of refractive index `4//3`.A light of `600nm`wavelength is falling on the slits having `0.45` mm separation .The lower slit `S_(2)` is covered by a thin glass sheet of thickness `10.4mu m` and refractive index`1.5`.the intereference pattern is observed ona screen placed `1.5m` from the slits are shown

(a) Find the location of the central maximum (bright fringe with zero path difference)on the y-axis.
(b) Find the light intensity at point `O`relative to the maximum fringe intensity.
(c )Now,if `600nm`light is replaced by white light of range 400 to700 nm find the wavelength of the light that from maxima exactly point `O`.[All wavelengths in this problem are for the given medium of refractive index `4//3` .Ignore dispersion]
