QUESTION #6 Refraction at Spherical Surfaces
In a long glass tube, mixture of two liquids A and B with refractive indices 1.3 and 1.4 respectively, forms a convex refractive meniscus towards A. If an object placed at 13cm from the vertex of the meniscus in A forms an image with a magnification of -2 then the radius of curvature of meniscus is :
