Predict/Calculate You are taking a photograph of a horse race. A shutter speed of 125 at f /5.6 produces a properly exposed image, but the running horses give a blurred image. Your camera has f -stops of 2, 2.8, 4, 5.6, 8, 11, and 16 (a) To use the shortest possible exposure time (i.e., highest shutter speed), which f -stop should you use? (b) What is the shortest exposure time you can use and still get a properly exposed image?

Two lenses that are 38.6 cm apart are used to form an image, as shown in the figure. Lens I is diverging and has a focal
length/--8.00 cm, lens 2 is converging and has a focal length/;+15.0 cm. A real object is placed 32 em to the left of
diverging lens. The height of the object is 10.0 cm

You desire to observe details of the Statue of Freedom, the sculpture by Thomas Crawford that is the crowning feature of
the dome of the United States Capitol in Washington, D.C. For this purpose, you construct a refracting telescope, using as
its objective a lens with focal length 87.5 cm. In order to acheive an angular magnification of magnitude 5.03, what focal
length fe should the eyepiece have?
cm
fe =
