Answer the following, "Will you help understand D", "Can you imagine", and "Put on the thinking Cap".

PUT ON THE THINKING CAP THINKING CAP Whoa. 1. A light ray, traveling parallel to a concave mirror's axis, strikes the mirror's surface. The reflected ray a. passes through the mirror's focal point b. again travels parallel to the mirror's axis c. travels at right angles to the mirror's axis d. passes through the mirror's center of curvature 2. An object is placed between a concave mirror and its focal point. What is the type and orientation of the image formed? a. virtual and inverted c. virtual and upright b. real and inverted d. real and upright 3. What kind of mirror is used in automobiles and trucks to give the driver a wider area and smaller image of traffic behind him? a. Plane mirror c. Concave mirror b. Convex mirror d. None of ab, and c 4. What type of mirror do dentists usually use to see clearly the images of our teeth? a. Plane mirror c. Concave mirror b. Convex mirror d. None of ab, and c 5. When a small object is placed on the principal axis of a concave mirror between the focus and the mirror (as in the figure below), the image formed is a. upright, magnified and virtual b. inverted, magnified and real c. inverted, reduced and real d. upright, reduced and real 6. Where should the object be placed in front of a concave mirror to form a virtual and magnified image? a. At the focus c. Between the focus and the vertex b. At the center of curvature d. Between the center of curvature and focusPUT ON THE THINKING CAP 7. An object is placed between a concave mirror and its focal point. What is the type and orientation of the image formed? a. virtual and inverted c. real and inverted b. virtual and erect d. real and erect 8. What kind of mirror is used by department stores to give a wider area and smaller image of the shoppers/buyers? a. Plane mirror 0. Concave mirror b. Convex mirror d. None of an, and c. 9. Where should an object be placed in front of a concave mirror so that the image will have the same size as the object? a. At the focus c. Between the focus and the vertex b. At the center of curvature d. Between the center of curvature and focus 10. The distance from the focal point to the vertex is to the distance from the center of the curvature to the focal point. a. twice as long as 0. equal b. half as long as d. four times as long as Part [1. Identify the L.0.S.T. for the ray diagram below. The blue line is the object and the red broken line is the image. Location of image: 1 .000...- Orientation of image: Size of the image: Type of image: \fMIRRORS Can you imagine? A person looks at his reflection in the concave side of a shiny spoon. Is it right side up or inverted? Does it matter how far his face is from the spoon? The bottom of the passenger side mirror on your car notes, "Objects in mirror are closer than they appear." Is OBJECTS IN MIRROR ARE CLOSER this true? Why? THAN THEY APPEAR In the figure at the right, the girl looks at a curve mirror that produces an enlarge image. What type of mirror was used here?WILL HELP YOU UNDERSTAND D Now let us summarize the description of the images formed in front of a curved mirror. For this activity base your answers from the previous activities. Answer the questions that follows. Image Location of Location Orientation Size Type Object (at C, at F, bet. (Upright or (Smaller, same, (Virtual or C&F, bet. F & V) Inverted) Larger) real A. CONCAVE object at C object between C&F object between F&V B. CONVEX object farther than C object between F & V Q: How does the location of the object affect the characteristics and location of the image formed in concave mirror? Convex mirror? Q: As mentioned in the SNEAK PEAK, small convenient stores use convex mirrors to monitor the sections between the shelves and other parts of the store. Why convex mirror is used for this case
