SUMMARY
The discussion centers on calculating the radius of curvature for the second surface of a lens with a power of -5.0D and a convex first surface radius of 15.0cm, made from a material with a refractive index of 1.50. The initial calculation yielded an incorrect radius of -0.10cm, while the correct answer is -6.0cm. The error arose from not converting units properly, as the focal length must be in meters, while the radius was mistakenly used in centimeters.
PREREQUISITES
