Across
- 2. the lowest point of the wave
- 5. the transfer of energy from a wave to a medium
- 8. need matter to transfer energy
- 10. the bending of a wave around the edges of an opening or an obstacle
- 11. do not need matter to transfer energy
- 12. energy move back and forward matter moves up and down
- 13. particles are spread apart
Down
- 1. the part of the compressional wave
- 3. the change in direction of a wave passing from a medium caused by changed of speed
- 4. height of the wave
- 6. the horizontal distance between the crest or trough
- 7. rhythmic disturbances that carry energy without carrying matter
- 9. the highest point
