Answer 2

Lens maker’s formula


Consider the thin lens shown here with the two refracting surfaces having radii of curvature equal to R1and R2 respectively.

The refractive indices of this surrounding medium and of the material of the lens are n1 and n2respectively.

Now using the result that we obtained for refraction at single spherical surface we get,
