An eyeglass lens is cut with one surface having a radius R1 and the other surface having a radius R2, with R1 < R2 . Both positive radii are measured from the same side with R2 being the side closer to the eye. Is this convex-concave lens a converging lens or a diverging lens?
 a. This is neither, since a lens cannot be made this way.
  b. This is a diverging lens.
  c. This can be either a converging or diverging lens, as more information is needed for a final determination.
  d. This is a converging lens.
