When air molecules get pushed together to form areas of high pressure resulting from a vibration source, the squishing of the molecules would be called
  1. When the molecules are pulled apart, this event is known as------
  2. The wave motion of sound travels in what manner? Air
  3. Water and light travels in this manner---- Transverse
  4. What is the polarity of a compression? Positive
  5. What are the three components of sound?
  6. The number of cycles a wave makes per second is classified as the ---------- of a sound. This is measured in what unit? Hz
  7. Waves that are close together produce higher or lower pitches than those that are farther apart? Higher
  8. Describe that acoustical properties of the doppler effect.
  9. The range of hearing for the average human being would be ----- to ----
  10. Double the cycle per second of a pitch and you will get the musical equivalent of the------ an octave higher, Second Higher
  11. The height of a wave will determine the -----Amplitude------ that is measured in the unit --------dB
  12. What is the volume measurement of the threshold of Pain? 120dB
  13. What is the unit measurement for the softest sound that is audible? 0dB
