QuestionWith a near point of 18.0 cm, a nearsighted professor can focus onrelatively nearby objects. Yet, with a far point 61.0 cm out, hecannot clearly see distant objects without optical aid.(a) Calculate the focal length (in cm) of a contact lens that wouldenable this professor to clearly view very distant objects. (Hint:Allow p to approach infinity in the thin-lens equation).cm(b) What power (in diopters) describes this contact lens?diopters(c) When this contact lens is in use, what is the professor's nearpoint (in cm)?cm(d) Which statement best describes the consequences of correctingdistance vision, when it comes to viewing nearby objects?(i)Contacts or glasses for nearsightedness have no effect upon howyou see very close objects.(ii)Contacts or glasses for nearsightedness make it easier to seevery close objects, too.(iii)Contacts or glasses for nearsightedness make it harder to seevery close objects.

Is this question set up wrong? I think the statement "The magnification of a book held 7.50 cm from a 10.0 cm-focal length lens is 3.00." is impossible using the lens equation 1/do + 1/di = 1/f and the equation for magnification m = -di / do.
An object is in front of a converging lens (f = 0.35 m). The magnification of the lens is m = 2.5. (a) Relative to the lens, in what direction should the object be moved so that the magnification changes to m = -2.5? (b) Through what distance should the object be moved?

A patient cannot clearly see any object that lies closer than 32.0 cm to her right 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? nearsightedfarsighted (b) If the eyeglass lens lies 2.10 cm in front of the patient's eye, what is the minimum distance p (in cm) separating the lens from an object she wants to see? (Give your answer to at least three significant digits.) cm (c) The patient is unable to focus clearly on anything closer than 32.0 cm to her eye (this being the patient's near point). The image formed by the eyeglass lens must therefore be 32.0 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.) cm (d) The image lies on the same side of the lens as the original object. Is the image real or virtual, and is its position q positive or…
