1. The ray diagram below shows a side view of a thin converging lens, a pencil, the image of the pencil, and an observer. Two rays from the pencil tip and two rays from the eraser have been used to determine the location of the image of the pencil. Image F Observer Object Thin lens a. What, if anything, can you tell about the (lateral) magnification of the image? In particular: . Is the magnification positive, negative, or zero? Explain how you can tell. . Is the absolute value of the magnification greater than, less than, or equal to one? Explain how you can tell. b. For an observer at the location shown, which would appear larger: the image of the pencil (with the lens in place) or the pencil (with the lens removed)? Explain. c. Are there some locations from which the image appears larger than the pencil and other locations from which the pencil appears larger than the image? If not, state that explicitly. If so, identify and clearly label two locations on the diagram above: one from which the image appears larger and the other from which the pencil appears larger. In either case, explain.2. An object is placed near two thin converging lenses (1 and 2). The focal points of the lenses are marked in the diagram below. Two rays are drawn from the top of the object (labeled point A) and through both lenses. These rays are parallel to each other as they enter the observer's eye. Object F1 F2 F2 A F1 Observer Thin lens 1 Thin lens 2 a. On the diagram above, draw an arrow to indicate the direction in which the observer must look in order to see the image of point A. (Clearly label the arrow you draw.) Explain how you determined your answer. What, if anything can you tell about the location of the image seen by the observer? Explain how you can tell
