Across
- 5. Rest point
- 6. The very bottom of the wave
- 7. A wave with an energy flow that moves the same direction as the wave
- 8. Waves that move through the crust of the earth
- 9. Most waves cannot move this
Down
- 1. The distance from the middle of the wave to the top
- 2. The distance from one peak to the next
- 3. the very top of the wave
- 4. The number of times a point on the wave passes the equilibrium
- 6. A wave with an energy flow that moves perpendicular to the wave's direction
