C.5 If you want to create a real image, which object location and mirror combinations could you use? Check all that apply.
Object in front of convex mirror
Object at distance over twice the focal length from concave mirror
Object between focal point and center of curvature of concave mirror
Object at distance less than focal length from concave mirror
C.6 You hold up your index finger very close to the surface of a concave mirror (inside the focal point). (a) As you move your
finger farther from the mirror, does the image of your finger get larger or smaller? (b) What happens to the image when the
distance between your finger and the mirror exceeds the focal length of the mirror? Select all that apply.
(a) Larger Smaller
(b) Stays the same

Section 0 - Introduction
0.1 Use the simulation in the interactive problem in this section to answer the following questions. (a) Where can you place the
object so that the image and object are on the same side of the mirror? (b) Where can you place the object so that the image
is smaller than the object? (c) Where can you place the object so that the image is larger than the object? Check all that(^592) Copyright 2000-2007 Kinetic Books Co. Chapter 31 Problems
