The otoscope is one of the simplestand most frequently used medicalinstruments by general practitionerphysicians and ear specialists (see thefigure below). The device contains aconverging lens with a power of 8.00diopters, a battery-powered integratedlight, and a disposable plasticspeculum.(a) What is the maximum distance (incm) from the otoscope lens that anobject can be placed if an enlargedand upright image is to be seen?(b) When placed inside a patient's ear,the lens of the otoscope is 3.00 cmfrom the tympanic membrane, theeardrum. By what percentage is a 1.00mm feature on the eardrum enlargedby the otoscope?(c) At what distance (in cm) from theeardrum would a feature on theeardrum be enlarged by 100%?

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…

A certain camera is able to focus on objects from 1.13 m to ∞o. Suppose you want to take an extreme close-up shot, with the camera 19 cm from the object. Find the focal length of a thin lens that could be placed directly in front of the camera lens such that the image of the close object would be in focus. (Let's denote the minimum and maximum values of the focal length by fmin and fmax, respectively.) 228 m -u I fmin = fmax = XX
