Across
- 4. low pressure area
- 5. travel fast through solids
- 8. Disturbances that transmit energy through matter
- 11. particles of the medium vibrate in a direction parallel to what the wave moves
- 12. can travel through a solid like Earth's crust
Down
- 1. particles of medium vibrate in direction perpendicular to what the wave moves.
- 2. high pressure points
- 3. type of mechanical wave in water
- 6. distance from midpoints to the crest
- 7. distance from one end of the compression to the end of the next
- 9. measured in hertz
- 10. can be calculated using wave equation
