Unit 13 Quiz#3
The diagram below shows a convex lens. The principal axis, focal point, and "center of curvature" (2F) are shown. The region on both sides of the lens is divided into twelve sections (labeled M, N, P, Q, R, S, T, U, V, W, X and Z). Five objects (labeled 1, 2, 3, 4, and 5) are shown at various locations about the lens. Use the diagram to answer the following six questions.
1. The image of object 1 would be located in section ______.
2. The image of object 2 would be located in section ______.
3. The image of object 3 would be located in section ______.
4. The image of object 4 would be located in section ______.
5. The image of object 5 would be located in section ______.
6. The lens would cause virtual images to be formed of object(s) ________.
7. Which of the following statements would not be true of virtual images?
8. Which of the following optical devices is not capable of forming a virtual image?
9. When an object is located at the focal point of a concave mirror, then ...
10. Diffuse reflection occurs because
11. Which one of the following phemomena does not illustrate the phenomenon of dispersion?
12. Which one of the following statements is a true statement about total internal reflection (TIR)?
13. The diagram at the right shows parallel incident rays striking a concave mirror. This diagram illustrates a phenomenon known as
14. The convex lens on Noah Formula's camera has a focal point of 35 mm. While on vacation, the camera is used to take a picture of a 1.00-meter high grizzly bear located a distance of 40.0 meters from the camera lens. If the image is to be focused upon the film, then what must be the distance from the lens to the film? How tall will the image of the bear be? (Note: 1 m = 1000 mm) PSYW
15. Consider the plane mirror below. Six objects (labeled A, B, C, D, E, and F) are located in front of the mirror. Which images of the six objects can be seen from the indicated eye position? Clearly circle all objects whose images can be seen. Support your answer with either an intelligent explanation or a clearly constructed diagram.
16. A ray of light is traveling through air (n=1.00) towards a lucite block (n=1.40). Trace the path of the light ray through the lucite block shown in the diagram below. Use Snell's law and be very accurate. Indicate all angles of incidence and angles of refraction on the diagram. For full credit, show all your work.
