WebQuestion: An object is placed between a converging lens and the focal point of the lens. Which of the following is true? The image is smaller than the object, real and inverted. The image is smaller than the object, virtual and inverted. The image is smaller than the object, virtual and upright. WebThen draw a ray from the edge of the object through the focal point on the left side of the lens and show it refracting so that it is parallel to the optical axis on the right side of the lens. Find the intersection of these two rays on the right side of the lens, and draw the image of the object (as shown in the video).
