Question
A glass sphere has a radius of 5 cm and a refractive index of 1.6. A paperweight is constructed by slicing through the sphere on a plane that is 2cm from the centre of the sphere and perpendicular to the radius of the sphere that passes through the centre of the circle formed by the intersection of the plane and the sphere. The paperweight is placed on a table and viewed from directly above by an observer who is 8cm from the tabletop. When viewed through the paperweight, how far away does the tabletop appear to observer
