Question

The human eye can be regarded as a single spherical refractive surface of
curvature of cornea 7.8 mm. If a parallel beam of light comes to focus at
3.075 cm behind the refractive surface, the refractive index of the eye is
1) 1.34
2) 1.72
3) 1.5
4) 1.61
the answer is 1.34 how???​

Answer 1

The eye can be regarded as a single refracting surface. The radius of curvature of this surface is equal to that of cornea (7.8mm) . This surface separates two media of refractive indices 1 and 1.34.
