2. PHYSICAL SCIENCE JEOPARDY

3. The highest point on a wave is the ____?
100

4. What is crest?

5. The lowest point of a wave is called the ______?
200

6. What is trough?
Slide 41

7. The height of a wave is called _____.
300

8. What is amplitude?

9. The distance from one crest to another or one trough to another is called a ______?
400

10. What is wavelength?

11. The number of waves that occur in a certain amount of time is called ____.
500

12. What is frequency ?

13. When a wave travels through a different medium such as helium, what will happen to the wave?
100

14. What is the wave will travel either faster or slower when in a different medium. In helium, since it is less dense than air, the wave would travel faster and have a higher frequency.

15. What is the frequency of this wave and what type of wave is this? 200

16. What is 3 and transverse?

17. Calculate the speed of a wave if its frequency is 2 Hertz and the wavelength is 4 meters.
300

18. What is speed = frequency x wavelength v = 2 x 4 v = 8 m/s?

19. How fast does sound travel in air? 400

20. What is 332 m/s or.2 miles/sec?

21. Explain why you would see lightning and hear the thunder a few seconds later? 500

22. What is sound waves travels slower than light waves
What is sound waves travels slower than light waves? Sound waves need matter to vibrate from one particle to the next, while light does not need matter to travel through.

23. Will sound travel in a vacuum?
100

24. What is no. Sound needs particles to bounce off of and in a vacuum there is empty space, just as in outer space.

25. Sound begins with a ____? 200

26. What is a vibration.

27. When sound travels and reflects back to you, you hear a(n) _____? 300

28. What is an echo?

29. What would be the angle of incidence for this wave
What would be the angle of incidence for this wave? What would the angle of reflection be? º

30. What is 50º and the angle of reflection would be like the line in green? 50º 40º

31. How does echolocation work for a bat or a whale ? 500 Hint

32. What is the bat or whale give off a high pitched screech or sound and they can calculate the distance between objects by the amount of time it takes the echo to reflect back to their ears.

33. When waves travel through a different medium and slow down, this is called?
100

34. What is refraction?

35. This fish net looks bent, Why? What is this called?
200
Daily Double

36. Light waves are traveling through a different medium, thus slow down & look bent. What is refraction?

37. When water waves bend around obstacles or openings it is called? 300

38. What is diffraction! Recall voices bending around the doorway & into the classroom.

39. When waves bounce it is called?
400

40. What is reflection?

41. Why is this strawberry seen as red?
500

42. What is red is reflected thus we see red
What is red is reflected thus we see red. All the other colors are absorbed by the strawberry.

43. What are the colors that are produced by the prism when white light shines through it?
100

44. What is ROYGBIV? Light is absorbed

45. This type of electromagnetic wave is used to heat your food in restaurants and is called ___. 200

46. What is Infrared?

47. The type of electromagnetic wave that can be used for radar, communication, and cooking is ___.
300

48. What is microwave?

49. The most dangerous form of electromagnetic waves for humans would be?
400

50. What is gamma waves?

51. Which electromagnetic wave has a wavelength of 10-2 m and 1010 Hz? 500

52. What is radar

53. Which medium has the slowest speed of sound? 100

54. What is air?

55. Describe each type of wrapping in terms of opaque, translucent, & transparent.
200 B A C

56. What is A transparent- can see through clearly, B - translucent- can see through, but not as clear, & C- opaque- cannot see through?

57. Explain why a pregnant woman should not have an X ray?
300

58. What is X rays can be dangerous to the unborn child by causing mutations in the cells that are multiplying rapidly in a growing fetus?

59. What is the only electromagnetic wave that humans can see?
400

60. What is the visible light spectrum? ROYGBIV

61. A wave that is amplitude modified (changed) would be considered as which type of radio wave?
500

62. What is AM radio ?
