  2. compression

  3. compression • A compression is the party of the sound wave where the particles are bunched together.

  4. frequency

  5. frequency • The frequency of a wave is the number of waves that pass a point in a certain amount of time.

  6. wavelength

  7. wavelength • A wavelength is the distance between a point on one wave and a similar point on the next wave.

  8. pitch

  9. pitch • A pitch is what makes a sound seem high or low.

  10. reflection

  11. reflection • Reflection occurs when light rays bounce, or reflect, from a surface back to our eyes.
