Textbook Question
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)?

When considering the location of images formed by lenses, we often like to employ ray tracing
diagrams. To do this we draw three rays of light and see where they intersect.
1. A ray parallel to the axis refracts through the far focal point.
2. A ray that enters the lens along a line through the near focal point emerges parallel to the axis.
3. A ray through the center of the lens does not bend.
This method was shown to you in class for the following situation:
An object and converging lenses with the distance to the object being greater than the focal length,
do > f.

Now you will complete the ray tracing diagram for an object that is closer than the focal length:

MIRROR/LENS EQUATION
1. Suppose that the height of the object is 3.00 cm at 20.0 cm from the concave mirror. What are the height and the distance of the image from the mirror if the focal length is 10.0 cm?
2. What is the local length of a convex mirror that produces an image that appears 20.0 cm behind the mirror when the object is 35.0 cm from the mirror?
3. Complete the given table. Show your solution. ( The table is provided in the picture.)
Please answer question nos. 1, 2 and 3.
Thank you!!
1.Place your object at a distance equal to the focal length (f) of your diverging lens. Where is your image located? Describe the type of image formed based on size, orientation, and condition and provide a screenshot of your set-up.
