the distance from the focal point of a lens or mirror to the reflects surface of the mirror or the centre point of the lens.
Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another.

Focal length is inversely proportional to refractive index of lens…
More the refractive index…more the rate of convergence and hence less is the focal length…
You could refer the lens formula..to understand the relation better…
