From the Light Walk home page, view the light activities which are listed there - light walk, pinhole viewer, pinhole camera, and slide projector activities. Read or (better yet) do one of the four activities. Connect the activity which you read (or do) with the principles discussed in the Geometric Optics lab. Write one paragraph in which you describe the activity, identify the principles by which it works, and associate those principles with at least one of the activities of the Geometric Optics lab.
