Image distance |v| vs object distance |u| curve for two biconvex lenses with same radii of curvatures is shown in the figure. If refractive index of lens 1 is 5/2, then refractive index of lens 2 is 0.5 x. find value of x.

Image distance |v| vs object distance |u| curve for two biconvex lense

1.	Image distance \|v\| vs object distance \|u\| curve for two biconvex lenses with same radii of curvatures is shown in the figure. If refractive index of lens 1 is 5/2, then refractive index of lens 2 is 0.5 x. find value of x.
