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. 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. The purpose of this portion of the lesson is to summarize these object-image relationships - to practice the L•O•S•T art of image description. We wish to describe the characteristics of the image for any given object location. The L of L•O•S•T represents the relative location. The O of L•O•S•T represents the orientation (either upright or inverted). The S of L•O•S•T represents the relative size (either magnified, reduced or the same size as the object). And the T of L•O•S•T represents the type of image (either real or virtual). 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:
Case 1: the object is located beyond the center of curvature (C)
Case 2: the object is located at the center of curvature (C)
Case 3: the object is located between the center of curvature (C) and the focal point (F)
Case 4: the object is located at the focal point (F)
Case 5: the object is located in front of the focal point (F)
If the image of an object is inverted and small then the object is said to be beyond the centre of curvature (i.e 2F)
Therefore we can say that ,
U>2F
