Consider two palne convex lanse of same radius of curvature and refrective index $n_{1}$ and $n_{2}$ respectively. Now consider two cases :

Case - I : When $n_{1} = n_{2} = n$ , then equivalent focal length of length is $f_{0}$
Case - II : When $n_{1} = n, n_{2} = n + Δ n$ , then equilivant focal length of lens is $f = f_{0} + Δ f_{0}$
Then correct options are :
