Optics and lenses
Q: "With unaided vision, a librarian can focus only on objects that lie at distances between 6.0 m and 0.37 m. Find the refractive power needed for each part of the bifocal eyeglass lenses (1. for the converging lens and 2.for the diverging lens) that will give the librarian normal visual acuity from 25 cm out to infinity. Assume the lenses rest 2.0 cm from his eyes."
