Instructions:
1. Load up the Java Lab from the web site shown above.
2. Select "Mirror"
3. Press toggle button to "+" (if it's not already shown) to indicate a converging (concave) mirror.
4. Press the "Reset" button. The value of p (the object's location) should be 20.0, the value of q (the image location) should be 20.0, the value of f should be +10.0, and "Paraxial" should be checked)
5. Move the object (the blue arrow) to the following positions (p): 30.0, 25.0, 20.0, 15.0, 10.0, and 5.0. (Click near tip of the object, and drag it to where you want to place it, and then release the mouse button.)
6. For each position of the object, record the location of the image (q) and the type of image (real or virtual), as well as the magnification (M) of the image.
7. Plot a graph showing the object's position (x-axis) versus the image position (y-axis).
8. Plot a graph of the object's position (x-axis) versus the magnification (y-axis).
9. Press the toggle button to "-" to indicate a diverging (convex) mirror.
10. Repeat steps 5 through 8 for this mirror.
11. Finally, write the report with your favorite word processor or text editor and submit is to the instructor. In this report discuss the effects produced when a mirror has a large curvature.
Use the "Sample Laboratory Report" as a guide in preparing your lab report.
