Across
- 3. less dense particles
- 5. the high point of a waves
- 6. the low point of a wave
- 9. move in matter perpendicular to the direction of the waves.
Down
- 1. more dense particles
- 2. the waves where the displacement of the medium is in the same direction as the direction of the travel of the wave
- 4. high or low wavelength
- 7. the distance from on crest to the next
- 8. the transfer of energy from one location to another through waves
- 10. the distance from one rest position to the crest, or from the rest position to the trough
