- To compare the graph with the equation, students can calculate
(1/Do + 1/Di) for each pair of images and object distances. If the values of (1/Do + 1/Di) are approximately equal, then the equation shown describes their data (and they can calculate f).
- The real image will lie on the wax paper.
- Depth of fluid is the range of object distances that will produce a sharp image. It depends on the lens’ focal length aperture (f- number) and the object distance.
