  9. Draw a ray.

  10. How long do you have to wait to see in the dark?

  11. Never will be able to see, nothing emitted

  12. Describe the conditions necessary to see light

  13. Has to reflect off an object and into your eyes

  14. Draw the light rays emitted from one point on a candle.

  15. How does a pinhole work? Draw the object and image.

  16. What causes the formation of shadows?

  17. When light shines on an object, some of the rays may be stopped while others pass on in a straight-line path

  18. What is the difference between a shadow and a semi-shadow?

  19. Shadow- clearly defined Semi-shadow- fuzzy, light can pass

  20. Draw the shadow. Is it a shadow or a semi-shadow?

  21. Shadow

  22. Draw the shadow. Is it a shadow or a semi-shadow?

  23. Semi-shadow

  24. What is an eclipse? Provide an example, include a diagram

  25. Solar eclipse: moon passes between earth and sun Lunar eclipse: earth passes between sun and moon

  26. What is the law of reflection?

  27. Angle of incidence = angle of reflection

  28. How big a mirror do you need to see your entire body? Include a ray diagram.

  29. A mirror half your height (diagram on board)

  30. What is the normal? Why is it so important?

  31. Normal = perpendicular to the surface; rays reflect about the normal

  32. A 50 cm dog stands 3 m from a plane mirror and looks at its image. Draw a ray diagram for the dog. Describe the image.

  33. Virtual, same size, same distance. Diagram on board

  34. Describe the process of triangulation. Where is it used in your everyday life? Why is it necessary for our study of optics?

  35. Triangulation = using multiple observers to pinpoint a source (ex: image location for a plane mirror, gps, satellite tv, etc)

  36. What type of image can a concave mirror form?

  37. Real or Virtual depending on location in relation to focal point

  38. Where is the focal point located for a convex mirror? What type of image is always formed?

  39. Behind the mirror, virtual image

  40. What type of mirror is this? Why is there a warning?

  41. Convex, diverging light increases vision but decreases size of car

  42. Locate the position, orientation, and type of image formed by an upright object held in front of a concave mirror of focal length +10 cm. The object distance is 54cm and is 10cm tall. Include a ray diagram.

  43. di = 12.27 cm M = - 0.23 hi= -2.3 cm

  44. Locate the position, orientation, and type of image formed by an upright object held in front of a convex mirror of focal length (-35) cm. The object distance is 40cm and is 17cm tall. Include a ray diagram.

  45. di = -18.66 cm M = 0.46 hi= 7.93 cm

  46. Describe how light bends as it changes mediums.
