Chapter 24.2, Problem 1TH
The top view diagrams at right were drawn by a student who is studying image formation by a plane mirror. Each diagram shows the location of an object and two lines of sight to the mirror.
For each diagram, determine whether or not the situation illustrated is possible. If a situation is possible, draw the location and orientation of the mirror.
Explain how you reached your conclusions.

Part A
The diagram below shows the situation described in the problem. The focal length of the lens is labeled f; the scale on the
optical axis is in centimeters.Draw the three special rays Ray1, Ray2, and Ray3 as described in the Tactics Box above, and
label each ray accordingly. Draw the rays from the tip of the object to the lens. Do not draw the refracted rays.
Draw the vectors starting from the tip of the object. The location and orientation of the vectors will be graded. The

Match the words in the left column to the appropriate blanks in the sentences on the right. concave convex long short larger smaller real virtual upright inverted in front behind diverge from converge to The spoon is a concave mirror with a smaller focal length. Your face is an object at a distance much larger than the focal length. The spoon reflects rays from your face to form a long inverted image that is virtual of the spoon. The rays do not stop at the image; they converge to the image plane and enter your eye. Thus what your eye is focused on is a virtual image of your face that is inverted (and also reduced in size).

This part is graded on completeness so just try it out even if you feel it is wrong. Notice it is important to not get confused between the rules for lenses and mirrors. 1. Consider a concave mirror. An object is placed at various object distances from the mirror. For each case, use ray tracing to determine the following characteristics of the image: * is it real or virtual? n is it upright or inverted? n is it smaller or bigger than the object (or the same size)? n where is the image located? (approximate location – does not have to be exact) Assume a concave mirror with a focal length of f=5cm. Make sure to use a ruler and follow the ray-tracing rules.
