A parallel incident beam falls on a solid glass sphere at near normal incidence.Show that the image in terms of the index of refractive `mu` and the sphere of radius R is given by
`(R(2-mu))/(2(mu-1))`

A parallel incident beam falls on a solid glass sphere at normal incidenc. Prove that the distance of the fianll image after two refractions is at a distance (2-mu)//2(mu-1)a from the outer edge of the sphere. Refractive index of the sphere is mu and radius of the sphere is a.
