Refraction and Lenses - Mission RL11 Detailed Help


An 'object arrow' (in RED) is placed in front of a diverging lens as shown in the diagram. Which image (in GREEN) represents the approximate location, size and orientation for such an object position?


 
The LOST Art of Image Formation:
A diverging lens produces images that always have the same characteristics regardless of where the image is located. The four characteristics that are important in the description of a convex mirror image are easily remembered by the mnemonic LOSTLocation, Orientation, Size and Type.


 
The collection of questions within this mission are straightforward. You likely have received a handout or a collection of class notes on the topic. Or perhaps you have constructed ray diagrams in class for the various locations and were able to draw conclusions regarding the image characteristics. You might have even made direct observations of actual images in lab investigations. A web page from The Physics Classroom Tutorial (see Hot Link section) exists that thoroughly addresses the topic. If you're having difficulty with this question, then be resourceful. Open your class notes, review lab observations, or use the link provided here to review the topic. Use the LOST model described in the Know the Law section. You will benefit greatly from the effort made to do so; and you will likely never miss a question on this mission and never have to refer to this help page again. In the end, you will find that a diverging lens image is not all that complicated; it always has the same characteristics regardless of where the object is placed.


 
The diagram shows an object located in front of the F location of a diverging lens. There are numerous images shown at various locations. Some images are larger than the object (magnified); other images are smaller in size (reduced). Some images are upright; other images are inverted. The goal is to use the LOST model to identify the location and characteristics of the image. Many images can be instantly ruled out because of an incorrect location. Others can be ruled out because of an incorrect orientation. Still others can be ruled out because of incorrect size. There is only one correct image for the given object location; your goal is to find it.
