  1. A ______wave is a wave in which the particles of the medium vibrate ______to the direction of wave motion.
  2. For an example, a wave moving horizontally through a ______causes the ______in the spring and anything attached to the coils to move ______.

  6. Card 5: low amplitude, low frequency
  1. Label the Diagram

  1. What happens to the air particles when the drumhead moves out after being hit?
  2. The air particles move perpendicular to the direction of the wave
  3. The air particles spread farther apart
  4. A compression is created in the air particles
  5. A rarefaction is created in the air particles
