6.10* A thick glass lens of index 1.50 has radii of +23 cm and +20 cm, so that both vertices are to the left of the corresponding cen- ters of curvature. Given that the thickness is 9.0 cm, find the focal length of the lens. Show that in general R₁ - R₂ = d/3 for such afocal zero-power lenses. Draw a diagram showing what happens to an axial incident parallel bundle of rays as it passes through the system.
