Across
  1. 4. a description of how high or low the sound seems to a person
  2. 7. the time it takes for one complete wavelength to pass
  3. 8. occurs when waves combine to form a new wave while they overlap
  4. 9. when two objects naturally vibrate at the same frequency
  5. 11. the distance between one point on a wave and the same point on the next wave; measured in meters
Down
  1. 1. a wave in which the particles of the medium move in a direction parallel to the direction in which the wave moves
  2. 2. the repeated back-and-forth movement of an object or substance
  3. 3. the number of vibrations per second; measured in Hertz (Hz)
  4. 5. a unit used to measure the “loudness” of a sound (dB)
  5. 6. how fast pressure waves of a sound travels; measured in meters per second:
  6. 10. a measure of how compressed or rarefied the medium becomes
