Spherical Mirror Equation #2

1. Which diagram best shows the location of point I, the image of the tip of the object arrow?

2. If the object shown in the problem above is 3 cm from a mirror that has a radius of 10 cm, what is the exact location of the image?

3. The image in question #1 is

virtual, upright, enlargedvirtual, upright, equal in sizevirtual, upright, reduced

4. If the object is 4 cm tall, how tall will the image be?

Refer to the following information for the next six questions.

An object is located at the center of curvature C of a concave spherical mirror with principal focus F. The focal length of the mirror is 0.10 meter.

5. At what distance from the mirror is the image located?

0.10 m0.20 m0.30 m0.40 m

6. Is the image formed real or virtual?

realvirtual

7. If the object is moved to a new location which is twice as far away from the mirror, what will happen to the size of the image formed by the mirror?

it will become smaller
it will become larger
it will remain the same size since the object will be the same size

8. As the object is moved from point C toward point F, the size of the image

decreasesincreasesremains the same

9. Where should the object be placed in front of the mirror so that it forms a real image that is twice as tall as the object?

10. Where should the object be placed so that it forms a virtual image that is twice as tall as the object?

Refer to the following information for the next question.

A convex mirror monitors the aisles of a store. The mirror has a radius of curvature of 0.50 meters.

11. Where will the image of a customer standing 10.0 meters in front of the mirror be formed?

-0.244 meters
-0.256 meters
-0.476 meters
0.526 meters

12. Which type of mirror can never form a real image?

concaveconvex

13. Which statement is true?

convex mirrors can only form enlarged virtual images
concave mirrors can only form reduced virtual images
plane mirrors can only form reduced virtual images
none of the above statements are true, they are all false statements

14. The only time an image cannot be formed by a mirror is when an object is placed _____ in front of a _____ mirror.
