Problem 8: People who do very detailed work close up, such asjewellers, often can see objects clearly at much closer distance than the normal 25 cm. Part (a) What is the power in D ofthe eyes of a woman who can see an object clearly at a distance of only ".5 cm? Assume the distance to her retina from the lens in her eye is 2.00 cm. P = Part (1)) What is the size in mm of an image ofa {3.95 mm object. such as lettering inside a ring. held at this distance? W = Pa rt (c) What would the size in mm of the image be if the object were held at the normal 25 cm distance? Ila-NI = Problem 9: Consider a patient who had laser vision correction that reduced the power of her eye by ".5 D, producing normal distant vision for her. Randomized Valiables AP = ".5 D What was the previous far point of a patient in meters? The power for normal r vision is 50.0 D. The distance of the image formation in the eye is 2.00 cm. FF 2 Problem 10: The contact lens prescription for a mildly farsighted person is U. "5 D. and the person has a near point of 29.0 cm. Randomized Variables Pc = (J. "5 D What is the power in D of the tear layer between the cornea and the lens if the correction is ideal taking the tear layer into account? Assume that a normal human has a near point of 25.0 cm. P: = Problem 11: Consider a 0.13 cm focal length microscope objective that is 0.22 cm from the object being viewed. Part_(a) What magnication is beingproduced by the objective? ino = Part (1)) What is the overallmagnification ifa 8x eypiece is used? m = Problem 12: Suppose you have a telecsope with a 85 cm focal length objective and a 2.25 cm focal length eyepiece. Randomized Variables ; = 2.25 cm Find the distance in centimeters between the objective and eyepiece lenses in the telescope needed to produce a final image very far from the observer, where vision is most relaxed. Note that a telescope is normally used to view very distant ob'ects. D =
