Refraction and Lenses - Mission RL9 Detailed Help

If an object is placed at a position between the F' point and the surface of a converging lens, then the image will be ____. List all that apply.

The LOST Art of Image Formation:
The characteristics of images formed by converging lenses is dependent upon the location of the object. Varying the object location results in different image characteristics. The important characteristics are easily remembered by the mnemonic LOSTLocation, Orientation, Size and Type. The general idea is that the principal axis can be divided into three regions - the region behind the 2F point, the region in front of the focal point and the region between the 2F point and the focal point. The characteristics of the image will be predictably the same whenever the object is within a given region, no matter where within the region it is. If the object is between regions - at the 2F point or at the focal point, then the characteristics of the image will be predictably different than if the object were in the region itself.

The collection of questions within this mission require a good deal of mental (and probably physical) organization on the part of a student. You likely have received a handout or a collection of class notes on the topic. Perhaps you even conducted a collection of laboratory observations. A web page from The Physics Classroom Tutorial exists that thoroughly addresses the topic. It is recommended that you take some time to organize yourself properly before answering these questions. Using a table or a diagram (see Hot Link section), describe the characteristics of an image for each of the regions and for the two points (2F and F) for a converging lens. Use the LOST model described in the Know the Law section. Once organized, 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.
