2. Instructions for using this template. Remember this is Jeopardy, so where I have written “Answer” this is the prompt the students will see, and where I have “Question” should be the student’s response. To enter your questions and answers, click once on the text on the slide, then highlight and just type over what’s there to replace it. If you hit Delete or Backspace, it sometimes makes the text box disappear. When clicking on the slide to move to the next appropriate slide, be sure you see the hand, not the arrow. (If you put your cursor over a text box, it will be an arrow and WILL NOT take you to the right location.)

3. Choose a category. You will be given the answer. You must give the correct question. Click to begin.

17. 0.25 s.

18. If a 220 Hz sound wave travels at 220 m/s – what is the wavelength?

19. 1 m.

20. If a wave has a frequency of 9 Hz, how many waves will travel past a given point in 3 seconds?

21. 27 waves.

22. What is the period of a wave traveling at 40 m/s with a wavelength of 5 m/s

23. 1/8s, or 0.125 s

25. 100 m/s

26. What kinds of waves can experience the Doppler Effect?

27. All waves.

28. Do you experience the Doppler Effect if the wave source is moving away from you?

29. Yes…it doesn’t matter which way the wave is moving.

30. What causes a sonic boom?

31. When an object is moving faster than the speed of sound.

32. When a plane is flying faster than the speed of sound, what is this called?

33. Supersonic

34. If you are in front of the Doppler rocket, the sound is at a higher ______ because the frequency of the waves is higher.

35. Pitch

36. What is the range of human hearing?

37. 20 Hz – 20,000 Hz

38. Can we hear infrasonic or ultrasonic waves?

39. No.

40. What kind of wave is a sound wave?

41. A longitudinal wave

42. What material does sound travel fastest in – steel, air, or water?

43. Steel

44. If the air is warm, does sound travel faster or slower?

45. Faster

46. T/F – In a longitudinal wave, the source of the vibration moves at right angles to the wave motion.

47. False

48. If a sound source has a high frequency, what can you say about the pitch, amplitude, and speed of the wave?

49. The pitch is higher, the amplitude isn’t affected, and the speed isn’t affected.

50. What is it called when things start to vibrate along with a source of a wave?

51. Resonance

52. When you get old like Mr. C, what happens to your ability to hear things?

53. It takes a nose dive…big time.

54. If an object is really soft, what effect does this have on it’s properties of reflection?

55. It doesn’t reflect very well.

56. Label the wavelength on the waves at the board.

57. Hmmm….how’d they do?

58. Draw a longitudinal wave on the board and label the compressions and rarefractions.

59. Hmmm…would this be good for the test?

60. Label the amplitude on transverse wave on the board.
