Which one of the following diagrams correctly illustrates the refraction of a normally incident ray of light through a glass slab?

Optical fibers, though bent in any manner, allows light to pass through. What is the inference that one can draw from it?

The radii of curvature of the spherical surfaces of a biconvex lens are $20 \mathrm{cm}$ and $30 \mathrm{cm}$. The refractive index of the material of the lens is $1.65$. If the lens is submerged in a liquid of refractive index $1.1$, its effective focal length will be

The minimum distance between object and it's real image formed by a convex lens is:
