Young`s double slit experiment is first performed in air and then in a medium other than air.It is found that 8th bright fringe in medium lies where 5th dark fringes lies in air The refractive medium of the meduum is-

As we all know that
Refractive index = wavelength in air / wavelength in medium
                            = width in air / width in medium
                   = position of fringe in air/position of fringe in medium
                        = n/(2n1-1)
                       = 8/9
