A physicist's right eye is presbyopic (i.e., farsighted). This eye can see clearly only beyond a distance of 89 cm, which makes it difficult for the physicist to read books and journals. Find the focal length and power of a lens that will correct this presbyopia for a reading distance of 25 cm, when worn 2 cm in front of the eye. focal length: ст power: diopters Is this a converging or a diverging lens? O converging O diverging
