I. The diagrams It right illustrate Top View Observer's View Top View Observer's View what an observer sees when n,\" \"m, from ".3," looking at a pencil through a lens. The observer's View is shown Pen .1 P m1 from two slightly different "' ' perspectives: one from the center. and one from the right. Is the image ofthe pencil located closer to.faher'am. or the some dirtanceam the observer than the pencil itself? Ifit is not possible to determine whether the pencil or its image is closer to the observer. state that explicitly. Explain your reasoning. 2. An object is placed near a converging lens as shown below. Each focal point of the lens is marked by an F. Two rays have been drawn to determine the location of the image of the obyect. Thin oonverging lens Continue the third ray shown on the diagram to Show the path through the lens and on the other side of the lens. Explain your reasoning. 3. A converging lens. a long-lament bulb, and a screen are arranged as shown in the perspective view diagram below. A sharp. inverted image of the lament ofthe bulb (not shown) appears on the screen when it is at the location shown. Bulb Lens Screen 3. Describe how, if at all. the image on the screen would change if an opaque mask were placed betWeen the lens and the bulb so it covers the top half of the lens. (See gure below.) Explain your reasoning. 3 Screen 1:. Suppose that, instead. the mask were pheecl between the lens and the screen. but themes]: still covers the top hnlf of the lens. Would the image on the screen change from what it was in part a? If so. how would it change? Ifnot. why would it not change? j E Bulb Lens
