Chapter 34: Q49P (page 1040)
An illuminated slide is held from a screen. How far from the slide must a lens of focal length be placed (between the slide and the screen) to form an image of the slide鈥檚 picture on the screen?
Distance from the slide at which the lens should be placed is .

In Fig. 34-26, stick figure O stands in front of a thin, symmetric lens that is mounted within the boxed region; the central axis through the lens is shown. The four stick figuressuggest general locations and orientations for the images that might be produced by the lens. (The figures are only sketched in; neither their height nor their distance from the lens is drawn to scale.) (a) Which of the stick figures could not possibly represent images? Of the possible images, (b) which would be due to a converging lens, (c) which would be due to a diverging lens, (d) which would be virtual, and (e) which would involve negative magnification?
An object is placed against the center of a thin lens and then moved away from it along the central axis as the image distance is measured. Figure 34-41 gives i versus object distance p out to . What is the image distancewhen ?
58 through 67 61 59 Lenses with given radii. An object stands in front of a thin lens, on the central axis. For this situation, each problem in Table 34-7 gives object distance , index of refraction n of the lens, radius of the nearer lens surface, and radius of the farther lens surface. (All distances are in centimeters.) Find (a) the image distance and (b) the lateral magnification m of the object, including signs. Also, determine whether the image is (c) real or virtual , (d) inverted from the object or non-inverted , and (e) on the same side of the lens as object or on the opposite side
17 through 29 22 23, 29 More mirrors. Object O stands on the central axis of a spherical or plane mirror. For this situation, each problem in Table 34-4 refers to (a) the type of mirror, (b) the focal distance , (c) the radius of curvature , (d) the object distance , (e) the imagedistance , and (f) the lateral magnification . (All distances are in centimeters.) It also refers to whether (g) the image is real or virtual localid="1662996882725" , (h) inverted or noninverted from O, and (i) on the same side of the mirror as object O or on the opposite side. Fill in the missing information. Where only a sign is missing, answer with the sign.
Figure 34-37 gives the lateral magnification of an object versus the object distanc from a spherical mirror as the object is moved along the mirror鈥檚 central axis through a range of values . The horizontal scale is set by . What is the magnification of the object when the object is from the mirror?
