A spherical surface of radius 30cm separates two transparent media A and B with refractive indiecs `1.33` and `1.48` , respectively. The medium A is on the convex side of the surface. Where should a point object the placed in medium A so that the paraxial rays become parallel after refraction at the surface?

Text Solution

Verified by Experts

`(1.48)/(oo)-(1.33)/(-x)=(1.48-1.33)/(30)`
`:. x=266cm`
