A patient cannot clearly see any object that lies closer than 31.0 cm to his left eye. However, the patient wishes to see objects as close as 20.0 cm with that eye. The patient requests eyeglasses to address the problem. (a) Is the patient nearsighted or farsighted? O nearsighted Ⓒfarsighted (b) If the eyeglass lens lies 2.06 cm in front of the patient's eye, what is the minimum distance p (in cm) separating the lens from an object he wants to see? (Give your answer to at least three significant digits.) 17.9 cm (c) The patient is unable to focus clearly on anything closer than 31.0 cm to his eye (this being the patient's near point). The image formed by the eyeglass lens must therefore be 31.0 cm from the eye. How far, then, (in cm) would the image lie from the lens? (Give your answer to at least three significant digits.) 28.9 cm
