Unformatted text preview: Draw a sketch and try to find a relationship that you can used to make predictions. For example, if you knew how far away an object was, could you determine its size based on the size of the image? 4) If you knew the sun was 150,000,000,000 meters away, could you use a pinhole camera, and your reasoning from 3) to estimate the diameter of the sun? If it’s a sunny day, we will try this. Guide to notes in your lab notebook: 1. Draw sketches of what you expect to see in steps 1) through 3) and draw diagrams of what you actually observe. Are they the same? 2. What does this tell you about the propagation of light? 3. Can you reconcile your observations with those you made in previous labs? 4. Work out a quantitative relationship between the size of the object viewed, the size of the image, and the distances involved....
