A mirror has a focal length of 10 cm. An object is located 15 cm to the left of the mirror.
1. Draw the ray diagram for this set-up.
2. Where is the image located?
3. Is the image real or virtual?
4. What is the magnification of the image?
5. If now a lens of focal length 20 cm is placed 20 cm to the left of the mirror, find the locations of the images formed?
6. What is the total magnification for the two images?
7. Describe the images, ie are they real or virtual, upright or inverted?
