5. This word means vibration.

6. What is oscillation?
A 100

7. An `Etude is a short complex musical composition.
Another ‘tude that refers to the amount of displacement from equilibrium for any vibrating body.
A 200

8. What is amplitude?
A 200

9. This word describes any force that acts to bring a body back to equilibrium

10. What is restoring?
A 300

11. The unit of vibrational frequency has this name, and these units.

12. What is Hertz, and cycles per second?

13. During a vibration, this is directly proportional to the restoring force.

14. What is the displacement from equilibrium?

15. The mass at the end of the pendulum string goes by this familiar man’s name.

B 100

17. Among many other pendulum experiments, he timed the swaying movement of a chandelier in a Pisa cathedral with his pulse.
B 200

18. Who was Galileo?
B 200

19. Generally speaking, this is the only factor that influences the period of a pendulum.
B 300

20. What is the length?
B 300

21. If on another planet, this aspect related to that planet can affect the pendulum period.
B 400

22. What is free-fall acceleration “g” on that planet?
B 400

23. At this pendulum position during its swing, restoring force and acceleration are said to be at maximum and speed is zero.
B 500

24. What is at maximum displacement?
(At equilibrium, the restoring force and acceleration are zero, and the speed is at the maximum.)
B 500

25. This is high point in a transverse wave form (above the equilibrium).
C 100

26. What is the crest of the wave?

27. This is how the wavelength measured?
C 200

28. What is from one point on the wave, such as on the crest, to another analogous or related point on the wave, such as on the next crest?
C 200

29. This describes the direction of a medium’s particle displacement, in relation to a transverse wave’s direction of travel in that medium.
C 300

30. What is perpendicular to the wave’s direction of travel?

31. DAILY DOUBLE
DAILY DOUBLE
C 400

32. All waves transfer this from one location to another.

33. What is energy?
C 400

34. This wave pattern, such as in a taut string, appears to be stationary as it is it moves between fixed points.
C 500

35. What is a standing wave pattern?
C 500

36. This is the type of wave form that carries sound energy.

37. What is longitudinal or compression?

38. This is an area of the longitudinal wave in which the particles in the medium spread out.

39. What is rarefaction?
D 200

40. This name is given to the changes in pitch, perceived by someone standing still, as a siren-blasting fire engine moves towards, and then past, that person.
D 300

41. What is the Doppler Effect?

42. The parts of this trigonometric wave are often compared to the portions of the sound wave.

43. What is the sine (sinusoidal) wave?

44. This is way a sonic boom is created as a jet breaks the sound barrier.

45. What is at supersonic speeds a pressure field is confined to a region extending mostly to the rear and extending from the jet in a restricted widening cone (called a Mach cone).
The sound waves combine behind the jet to form a “wake” which causes the loud boom.
D 500

46. This is the lower part of the transverse wave form.
(below the equilibrium)
E 100

47. What is a trough?
E 100

48. As the wavelength increases this happens to the frequency.

49. What is the frequency decreases?

50. (You must give both terms.)
The point in a standing wave that remain stationary, and the areas that are vibrating.
(You must give both terms.)
E 300

51. What are nodes (stationary points) and antinodes (areas of vibration)?

52. This happens to wave pulse amplitudes during constructive interference?

53. What is they add together?

54. When two wave pulses pass on opposite sides of the equilibrium position, and they completely cancel each other out, this has happened.
E 500

55. What is complete destructive interference?

56. This is the reflection of sound arriving sometime after the original directed sound.

57. What is an echo?
F 100

58. This is the bending of waves as they travel from one medium to another.

59. What is refraction?
F 200

60. This is bending of waves around obstacles or through openings.

61. What is diffraction?
F 300

62. This is happens when an object, vibrating at the same natural frequency of another object, causes the second object to vibrate.
F 400

63. What is resonance?
F 400

64. The process of causing a disturbance which produces a wave.
