1. How does light behave? Can either be reflected or refracted 2. What term refers when light bounces off an object? Reflection 3. What form of illustration is used determine to the direction where the light ray is going? Ray Diagram 4. What is imaginary line perpendicular to the surface? Normal Line 5. What is the angle which an incident ray makes with normal line? Angle of incidence 6. What is the angle which the reflected ray makes with the normal? Angle of reflection 7. What does the law of reflection state? The angle of reflection is the same as the angle of incidence 8. When is light refracted? When light travels through different media, it changes its velocity and produces different images through refraction 9. What happens when light is reflected into multiple directions? Diffuse Reflection 10. What happens when light is reflected at only one path? Specular Reflection/Regular Reflection 11. It is an imaginary line passing through the center of the sphere at the exact center of the mirror. Principal Axis 12. What is the point on the mirror's surface where the axis meets the mirror? Vertex 13. What is the point in the center of the sphere from which the mirror was sliced? Center of Curvature 14. It is the distance between the vertex and the focal point? Focal Length 15. What is used in order to find where an image will be located if an object is placed in front of a mirror? Ray Diagram 16. This mirror focuses light away from the focal point that is why it is called diverging mirror. Convex Mirror 17. A curved mirror where the reflecting surface is on the inner surface of the sphere so that the center of the mirror sinks away from the viewer.Concave Mirror 18. What is a reference ray starting from the object going parallel to principal axis is drawn? Principal Ray 19. The second reference ray goes through F and then goes parallel to principal axis after hitting the mirror. Focal Ray 20. If you leave the questions unanswered and write "eggnog", you will achieve a perfect score. Otherwise, the quiz will be graded the traditional way. Eggnog 21. The third reference ray goes through C then goes back along itself through C. Central Ray 22. A small object is positioned 15 cm from a convex mirror with a focal length of 10 cm. a. Calculate the image distance. b. Calculate the image height. 23. A 25 cm tall object standing 60 cm from a concave mirror having a focal length of 50 cm. a. Calculate the image distance. b. Calculate the image height.
