Across
  1. 2. Moves perpendicular to the direction the wave is traveling
  2. 5. Sound travels slowest through this because the particles are far apart, so vibrations lose energy as they move
  3. 6. Distance between two crests (or troughs)
  4. 8. Lowest point of the wave
  5. 11. Volume (loud / soft)
  6. 12. Sound travels best through this because the particles are close together.
  7. 14. Highest point of the wave
Down
  1. 1. Middle line the wave vibrates around
  2. 3. Moves parallel to the direction the wave is traveling
  3. 4. How many waves pass in 1 second
  4. 6. a way energy moves from one place to another without moving the matter.
  5. 7. Sound travels well through this because the particles are close together, but not as tightly packed as in solids.
  6. 9. anything that has mass and takes up space.
  7. 10. how high or low a sound is, and it depends on the frequency of the sound waves.
  8. 13. material that a sound wave travels through, such as a solid, liquid, or gas.
