2. It’s the frequency of a sound wave. A sound wave has this form.

3. 1 PT Pitch

4. Mechanical waves such as sound waves travel fastest through this

5. 2 PT Solids (the particles are closest together).

6. A sound wave is this type and form of wave.

7. 3 PT Mechanical and longitudinal (or compressional)

8. It’s another name for the energy of a wave; related to the amplitude

9. 4 PT Intensity

10. It’s the spread-apart portion of a sound wave

11. 5 PT rarefaction

12. Loudness is measured in these units

13. 1 PT Decibels (dB)

14. This wave phenomenon is caused by a shift in frequency due to the motion of the source of a wave relative to the observer.

15. 2 PT The Doppler Effect

16. It’s the direction a galaxy is moving when the galaxy is perceived to be red shifted.

17. 3 PT Away from the observer

18. Ships use this technology with sound waves to locate submarines under water.

19. 4 PT SONAR

20. The character of this determines the speed of any wave.

21. 5 PT The medium through which the wave travels

22. The unit for frequency (and pitch)

23. 1 PT Hertz (Hz)

24. It’s the type of wave shown below

25. 2 PT transverse

26. It’s the speed of a sound wave that has a frequency of 33.3 Hz and a wavelength of 10 m.

27. 3 PT 333 m/s

28. It’s the type of relationship that exists between frequency and wavelength

29. 4 PT Inverse relationship

30. The number of nodes, antinodes and wavelengths shown below

31. 5 PT 4 nodes, 3 antinodes and 1 ½ wavelengths

32. Sound waves and seismic waves represent this broad class of waves.

33. 1 PT Mechanical waves

34. The tiny hairs in this part of the ear resonate to different frequency

35. 2 PT The Cochlea

36. Changes in the tension or length of the vibrating medium causes this wave charcteristic to change

37. 3 PT Pitch

38. It’s the beat frequency produced by 441 Hz and 448 Hz tuning forks

39. 4 PT 7 beats per second

40. A radio wave is an example of this broad wave category

41. 5 PT Non-mechanical wave

42. It’s the normal audible range of hearing for humans

43. 1 PT 20 – 20,000 Hz

44. It’s the two terms used to describe frequencies above and below our normal range of hearing

45. 2 PT Infrasound (below) and Ultrasound (above)

46. These types of waves travel slowest through solids and fastest through a vacuum

47. 3 PT Non-mechanical waves (light waves or electromagnetic waves)

48. This wave phenomenon develops when the vibrations of one object match the natural frequency of another object, causing it to increase in amplitude.

49. 4 PT resonance

50. This wave phenomenon occurs when two identical waves constructively and destructively interfere to form nodes and antinodes.

51. 5 PT Standing waves
