Chapter 10.6, Problem 3bT

Draw a ray diagram that shows how to determine the location of the image that you observed above. Your diagram need not be drawn exactly to scale, but should correctly show the location of the object relative to the observer and to the lens and its focal points.

1. On the basis of your ray diagram, which is farther from the observer: the image or the object?

Is your answer consistent with your observations from pan A? If not, resolve the inconsistency.

2. Does a magnifying glass simply make an object appear closer (i.e., does it simply form an image of the object that is closer to you than the object itself)? If not, what does it do?

3. How can you tell from your ray diagram which would appear larger: the image of the pencil (with the lens in place) or the pencil (with the lens removed)?
