Hope u like my process
======================
If a lens is surrounded by air,
It's focal length is calculated or is given by,
Where f = focal lenght;
=> n = refractive index of lens.
=> r1 and r2 are the radius of curvatures.
_________________________
If the lens has n2 and is surrounded by refractive index n1,
we can write focal length as,

Hope this is ur required answer
