Across
- 3. low pressure area. particles of the wave spread apart
- 6. the particles of the medium vibrate in a direction parallel to the direction that the wave moves
- 11. the particles of the medium vibrate in a direction perpendicular to the direction that the wave moves
- 12. the ability to do work
- 13. the distance from one crest to the next
Down
- 1. high pressure area. particles of the wave crowd together
- 2. disturbances that transmit energy through matter
- 4. the distance from midpoint to the height of a crest (or bottom of a trough)
- 5. the highest part of a wave
- 7. the number of crests that pass a certain point in a given amount of time
- 8. the lowest part of a wave
- 9. the matter through which a mechanical wave can travel
- 10. something that has mass and takes up space
