11. F is the focal point
12. The dashed line is the
principle axis
13. The rays will be
reflected through point F
when they are parallel to
the principal axis.
14. The image will be
between C and F.
15. It will be + b/c the image
is on the same side of the
mirror as the object.
Section 17-2 Cont..
16. It will be real. Light
converges at the
image b/c d is +
17. The image will be
reduced b/c the object
is beyond point C.
18. The value of hi will
be lower b/c the
object is beyond point
C.
19. True
20. Diverge
21. True
22. Virtual
23. Inverted
24. smaller
Section 17-2 Cont.
25. A convex mirror produces a virtual image b/c the
reflected rays always diverge.
26. The image is always smaller than then object itself and
thus appears to be farther away. The image actually is
closer to the mirror than the object.
27. They enlarge the area, or field of view, that the observer
sees. Also, the field of view looks similar from any angle
of the viewer off the principal axis.
28. The focal length is - b/c the focal point is behind the
mirror.
29. Both have images with virtual negative image
distances. Plane mirror images are the same size as the
object and the same distance, whereas convex mirror
images are smaller than the object and closer to the
mirror than the object
