In Example 27-4, a person has a far-point distance of 323 cm. If this person wears glasses 2.00 cm in front of the eyes with a focal length of -321 cm, distant objects can be brought into focus. Suppose a second person's far point is 353 cm.
(a) Is the magnitude of the focal length of the eyeglasses that allow this person to focus on distant objects greater than or less than 321 cm? Assume the glasses are 2.00 cm in front of the eyes.
(b) Find the required focal length for the second person's eyeglasses.
