The left end of a long glass rod 6.00cm in diameter has a convex hemispherical surface 3.00cm in radius. The refractive index of the glass is 1.60. The rod is immersed in a liquid. An object 90.0cm from the vertex of the left end of the rod and on its axis is imaged at a point 1.60m inside the rod.
A) What is the refractive index of the liquid?
