  4. 8. When wave energy passes through a medium.
  5. 9. When light changes direction as it is transmitted, or travels from one medium to another.
  6. 12. When wave energy bounces off a medium, causing the wave energy to change direction.
Down
  1. 1. The energy input to that which causes the wave disturbance. The location of the originating energy.
  2. 2. When wave energy is trapped in a medium and doesn’t pass through.
  3. 4. A detector of wave energy, which could be natural (ears, eyes) or designed (microphone, camera).
  4. 5. The matter through which waves travel. The matter can be solid, liquid, or gas (e.g., water or air).
