The following questions pertain to the image characteristics of all types of mirrors discussed in this unit - plane mirrors, concave mirrors, and convex mirrors. Use your understanding of the object-image relationships for these three types of mirrors to answer the questions. The diagram below shows a spherical surface that is silvered on both sides. Thus, the surface serves as double-sided mirror, with one of the sides being the concave and one being the convex side. The principal axis, focal point, and center of curvature are shown. The region on both sides of the mirror is divided into eight sections (labeled M, N, P, Q, R, S, T, and W). Five objects (labeled 1, 2, 3, 4, and 5) are shown at various locations about the double-sided mirror. Use the diagram to answer the questions #1-6.
1. The image of object 1 would be located in section ______. M、 N、 P、 Q、 R、 S、 T、 W 2. The image of object 2 would be located in section ______. M、 N、 P、 Q、 R、 S、 T、 W 3. The image of object 3 would be located in section ______. M、 N、 P、 Q、 R、 S、 T、 W 4. The image of object 4 would be located in section ______. M、 N、 P、 Q、 R、 S、 T、 W 5. The image of object 5 would be located in section ______. M、 N、 P、 Q、 R、 S、 T、 W 6. The double-sided mirror would cause virtual image to be formed of objects ________. M、 N、 P、 Q、 R、 S、 T、 W 7. How can a plane mirror, concave mirror, and/or convex mirror be used to produce an image that has the same size as the object？ 8. How can a plane mirror, concave mirror, and/or convex mirror be used to produce an upright image？ 9. How can a plane mirror, concave mirror, and/or convex mirror be used to produce a real image？ 10. The image of an object is found to be upright and reduced in size. What type of mirror is used to produce such an image？
To summarize what you have learned in lesson 6-10, we would like to ask you to make a presentation introducing your recent work and life.
