Problem: Without a corrective lens a certain farsighted person can't focus clearly on objects that are closer to her eye than 80.0 cm. What is the magnitude of the focal length of the contact lens that will allow this person to see clearly objects that are 25.0 cm from her eye, and is the lens converging (f > 0) or diverging (f < 0)?Ans. |f| = converging or diverging?
