4.1 Flat Mirrors Using your flat mirror, perform ray tracing for a number of incident angles (say, 5). Measure the reflected angles to confirm or refute the equality of I and R. What is your largest source of uncertainty? 4.2 Curved Mirrors For both the concave and convex mirrors, determine the focal lengths by the parallel ray construction method, and compare this to the focal length determined from the radius of curvature. Assuming the mirror is a segment of a circle, you can determine the radius of curvature r by measuring the chord c and the height h of the segment the variables are defined in Figure 3. The radius is positive for concave mirror, and negative for a convex mirror. Now that you have determined the focal length, use your lasers to recreate the image construction outlined in Figure 2. There are three cases you should consider: for the convex mirror, find the location and size of the virtual image; for the concave mirror, determine the location and size of the images for objects that are closer to and further from the mirror than the focal point. For all three cases, measure p and q, as well as the transverse heights of the objects and images.
