A 4.0-cm-tall object is 15 cm in front of a convex
mirror that has a -25 cm focal length.
In the figure, the convex lens has a focal length of 20.4 cm.

a. Draw a careful ray tracing diagram, with a ruler, to find the image formed.
b. Is the image larger or smaller than the object?
c. Now calculate the image distance and magnification, numerically
• State what concept or equation you are using and write the general equation.
• Define all the variables in words and identify the values of all known variables.
• Show your work, include exactly 3 significant figures, and include units.
d. State if your answer to b agrees with your calculations. Explain your reasoning in 1-2
sentences.
e. Suppose you want to increase the magnification of the image. How could you adjust
the location of the object and/or lens. Explain your reasoning in 1-2 complete
sentences.
In the following three scenarios, an object is located on one side of a converging lens. In each case, you must determine if the lens forms an image of this object. If it
does, you also must determine the following.
• whether the image is real or virtual
• whether the image is upright or inverted
• the image's location, q
• the image's magnification, M
The focal length is f = 29.0 cm for this lens.
Set both q and M to zero if no image exists.
Note: If q appears to be infinite, the image does not exist (but nevertheless set q to 0 when entering your answers to that particular scenario).
(a) The object lies at position 29.0 cm. (Enter the value for 9 in cm.)
9 = 0
M = 0
