    Finding Image for a Thick bi-concave Lens

    Homework Statement A bi-concave lens (n=2) has radii of 15cm and 25cm, and an axial thickness of 6-cm. Use the thin-lens equation to see how far off it is in determining the final image location. Homework Equations n1/so + n2/si = (n2 – n1)/R; (n-1)(1/R1 – 1/R2) = 1/f The...
