Question

A point object $O$ is kept at a distance of $OP = u$. The radius of curvature of the spherical surface $APB$ is $CP = R$. The refractive index of the media are $n_{1}$ and $n_{2}$ which are as shown in diagram. Then, [image:9_image38.emf] (1) If $n_{1} > n_{2}$, image is virtual for all values of $u$ (2) If $n_{2} = 2n_{1},$ image is virtual when $R > u$ (3) The image is real for all values of $u,\ n_{1}$ and $n_{2}$.
