- 5. Waves that use matter to move or transfer energy.
- 8. A substance or matter through which a wave travels.
- 10. Waves that move through empty space (vacuum) or use matter to transfer energy.
- 12. When a wave passes from one medium into another and changes direction.
- 13. The number of complete waves that pass a point in a certain time.
Down
- 1. When a wave bounces back after striking something.
- 2. The ability for two waves to combine and make a new wave when they overlap.
