b. hertz c. low note d. transverse wave e. high note f. longitudinal wave g. mechanical wave h. decibels i. compression j. frequency k. rarefaction l. wavelength m. amplitude n. pitch 9. waves that require a medium to travel are known as 10. waves in the air caused by vibration 11. waves that move in one direction, but vibrate up and down 12. waves that move in one direction, and vibrate left and right 13. the distance between one wave and the next 14. how often a wave passes a certain point 15. the intensity of sound is measured in this unit 16. the frequency of sound is measured in this unit 17. this distance that the particles of a medium vibrate from their resting point 18. a sound wave with a high frequency would be heard as a 19. a sound wave with a low frequency would be heard as a 20. part of a sound wave in which particles are compressed together 21. part of a sound wave in which particles are spaced apart 22. humans hear the frequency of sound as 23 24 25.

Explanation:

1. Mechanical waves require a medium to travel.
2. Sound waves in air are longitudinal waves caused by vibration.
3. Sound waves in air are longitudinal waves caused by vibration.
4. Transverse waves move in one - direction and vibrate up and down.
5. Transverse waves move in one - direction and vibrate left and right.
6. Wavelength is the distance between one wave and the next.
7. Frequency is how often a wave passes a certain point.
8. The intensity of sound is measured in decibels.
9. The frequency of sound is measured in hertz.
10. Amplitude is the distance that the particles of a medium vibrate from their resting point.
11. A high - frequency sound wave is heard as a high note.
12. A low - frequency sound wave is heard as a low note.
13. Compression is part of a sound wave where particles are compressed together.
14. Rarefaction is part of a sound wave where particles are spaced apart.
15. Humans hear the frequency of sound as pitch.
