One whose hollowed-out side is silvered. (a) Can the magnification of a real image formed by such a mirror ever be greater than one? (b) Can the magnification of a virtual image formed by such a mirror ever be a number greater than zero but less than one? If you answer yes to one of these questions, give an example with a ray diagram to prove that you’re right. If you answer no, explain why it’s not possible. (b) Problem 7. 50 Chapter 3 Images 10 All of the curved mirrors shown in this chapter were hollowed out, like a dish, but it’s also possible to have a mirror that bulges outward.

When I did this, I was 52 The same setup viewed from the side. pointer is directly above the other. Chapter 3 Images able to locate the image’s position to within about a millimeter, and I got good agreement between the parallax method, opening one eye at a time, and depth perception, with both eyes open. B Changing the location Make a ray diagram, showing how each ray moves through the water, is refracted, and goes off through the air. 1 to predict whether the image should be ++ or +−. If you have time, do the other method too, and verify that you get the same answer.
