mall bulb is placed in front of a convex lens 39 Optics HW-139 a. Suppose that the bulb is placed as shown. Using all three principal rays draw an accurate ray diagram to determine the location of the image. Label the image location. Small bulb Lens b. Repeat part a for the case shown at right, in which the bulb is farther from the lens. Small bulb Lens 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. c. d. The light bulb is placed at one focal point of the lens as shown at right. Small bulb SF at focal point Draw at least five 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?)Explanation / Answer
(a)
when the bulb in located in front of the focal point of the converging lens, its image is an upright and enlarged image that is located on the object's side of the lens.
