Aa v 2 - V a AaBbCcDdEe AaBbCcDdEe AaBbCcDo A V D V A v = Normal No Spacing Heading 1 Presbyopia is the tendency to gradually become far-sighted (hyperopic) as you age. If you have normal vision when you are young, you have a near point of 25 cm. A. If the distance between your eye's lens and retina is 1.65 cm, what is the focal length of your eye's lens when you look at an object at your near point? f = 1.55 cm B. As you get older, suppose that the near point of your eye increases to 44 cm. What is the focal length of your eye's lens when you look at an object at your near point now? f = 1.59 cm C. With your near point at 44 cm, what is the focal length of the corrective lens (placed directly in front of your eye's lens) which you would need to look at an object that is 25 cm in front of your eye? f = 57.9 cm D. As you continue to age, the corrective lenses will no longer be sufficient to allow you to see an object that is 25 cm in front of your eye. When you are wearing your corrective lenses, suppose that you can now see objects only if they are no closer than 42 cm in front of your eye. What is the actual near point of your eye now? N = cm What is the focal length of your eye's lens that corresponds to this new near point? f = 1.63 cmA microscope is a device where a first lens makes a real image of an object, and that real image is then viewed with a second lens used as a magnifying glass to make a virtual image that is enlarged. The picture shows the two converging lenses of a compound microscope: the objective lens (on the left) near which the object to be viewed is placed, and the eyepiece lens (on the right) which functions as the magnifying glass. The obj 'x"), the eyepiece lens has a focal length feye (with focal points indicated by an "o"), and the two lenses are separated by a distance L. The picture may not be to scale, but it will at least allow you to correctly determine the kinds of Ima X A. The image formed by the objective lens is real and inverted V B. We use the image formed by the objective lens as the object for the eyepiece lens. The eyepiece lens then forms its own image. This image formed by the eyepiece lens is a virtual |image. For the eyepiece lens to form this kind formed by the objective lens? This answer has not been graded yet. C. The distance between the lenses is L = 15 cm, and the focal lengths are fobj = 1 cm and feye = 8 cm. The object to be viewed, a cell, is placed a distance of 1.143 cm in front of the objective lens. What is the image distance of the objecti obj cm D. How far is the objective lens image from the eyepiece lens? Deye = cm E. What is the magnitude of the distance between the eyepiece lens and the image that it forms? Veyel = cm Is the image formed by the eyepiece lens to the left or the right of the eyepiece lens? left F. What is the magnification due to each individual lens? mobj = meye = G. The total magnification is the product of the magnification due to each individual lens, and it is the ratio of the final image height over the original object height. If you are viewing a cell with a size of 10 um, what is the size (absolute value) eyepiece? size = Viewing Saved Work Revert to Last Response COLS Submit Answer are young, you have a near point of 25 cm.a real image of an object, and that real image is then viewed with a second lens used as a magnifying glass to make a virtual image that is enlarged. compound microscope: the objective lens (on the left) near which the object to be viewed is placed, and the eyepiece lens (on the right) which functions as the magnifying glass.
