6. A Ray of light from the left reflects off mirror M in the figure below. Which point (A-D) will the reflected ray pass through? Tip: draw a normal to the mirror surface where the ray reflects. A B M 1. Suppose that you want to take a photograph of yourself as you look at your image in a 7. The diagram below represents a person mirror 2m away. How far from the mirror is looking at the reflection of an object in a the image? mirror. Where does the image appear? A. Im Object B. 2m O A C. 4m D. 8m B 2. For what distance should the camera lens be M focused? (ie, how far away from the camera is the image) OD A. Im OC B. 2m C. 4m 8. Off in the distance you see two water tanks, D. 8m that appear to be the same size, but can't tell their relative distance. One is blue, the other 3. If you are 1.8m tall, what is the size of the red. While you walk to the right the red tank image? appears to move to the left. Which tank is A. 0.9 m closer? B. 1.8 m A. The Red water tank C. 3.6 m B. The Blue water tank D. 4.5 m C. Cannot be determined 4. The law of reflection states that Which tank is bigger? A. 01 =0, A. The Red water tank B. 0, = 0,2 B. The Blue water tank C. Cannot be determined C. sino, = sino, D. sino, = sin20, 10. To find an image by ray tracing requires A. one ray 5. In optics, we almost always measure angles B. two rays between light rays and the surface they strike C. three rays from D. four rays A. Normal to the surface B. Parallel to the surface C.
