![]() Light rays actually converge at the image location. In this case, the absolute value of the magnification is less than 1. Earlier in Lesson 2, the term magnification was introduced the magnification is the ratio of the height of the image to the height of the object. If the object is a six-foot tall person, then the image is less than six feet tall. In this case, the image is reduced in size in other words, the image dimensions are smaller than the object dimensions. That is to say, if the object is right side up, then the image is upside down. In this case, the image will be an inverted image. Regardless of exactly where the object is located, the image will be located in the specified region. When the object is located at a location beyond the center of curvature, the image will always be located somewhere in between the center of curvature and the focal point. Case 5: the object is located in front of the focal point (F).Case 4: the object is located at the focal point (F).Case 3: the object is located between the center of curvature (C) and the focal point (F).Case 2: the object is located at the center of curvature (C).Case 1: the object is located beyond the center of curvature (C). ![]() The best means of summarizing this relationship between object location and image characteristics is to divide the possible object locations into five general areas or points: T represents the type of image (either real or virtual).T represents the relative size (either magnified, reduced or the same size as the object).T represents the orientation (either upright or inverted).We wish to describe the characteristics of the image for any given object location. The purpose of this portion of the lesson is to summarize these object-image relationships - to practice the L Perhaps you noticed that there is a definite relationship between the image characteristics and the location where an object is placed in front of a concave mirror. Previously in Lesson 3, ray diagrams were constructed in order to determine the general location, size, orientation, and type of image formed by concave mirrors.
