I. A small bulb is placed in front of a convex lens. a. Suppose that the bulb is placed as shown. Using all three principal rays. draw an accurate ray diagram to F F determine the location of the image. Label the Small bulb image location. Lens b. Repeat part a for the case shown at right, in which the bulb is farther from the lens. F Small bulb Lens c. Suppose that in each case above you were to place a small paper screen at the image location. What you would see on the screen in each case? Imagine that the room is dark except for the small bulb. d. The light bulb is placed at one focal point of the lens as shown at right Small bulb F Draw at least five an focal point rays from the bulb that pass through the lens. Lens Where is the image located in this case? Explain. (Hint: How are the rays that have passed through the lens oriented? From where do these rays appear to have come?)2. Two thin convex lenses ( I and 2) and a small object are arranged as shown. a. Use the three principal rays to determine the location of the image of the object produced by lens 1. Object FI F2 F2 Thin lens 1 Thin lens 2 b. Treat the image produced by lens I as an object for lens 2. Use the three principal rays to determine the location of the image of this object produced by lens 2. Is this image produced by the pair of lenses real or virtual? Explain your reasoning. c. Repeat parts a and b for the case in which lens 2 is replaced with a different lens (lens 3), as shown below. Object F3 F3 - 4- -- FI Thin lens 1 Thin lens 3 Is the image produced by the pair of lenses real or virtual? Explain your reasoning
