A spherical surface of radius 30 cm separates two transparent media A and B with refractive indices 1'33 and 1.48 respectively. The medium A is on the convex side of the surface. Where should a point object be placed in medium A so that the paraxial rays become parallel after refraction at the surface ?

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`mu_2/v-mu_1/u=(mu_2-mu_1)/R`
`(-1.33)/u=0.15/(30xx100)`

`u=20xx0.35/100=-266cm`
