Across
- 2. number of wavelengths that pass a point each second
- 6. wave travels through matter or through empty space
- 9. Wave travels only through matter
- 10. Position the position of an undisturbed particle; particles are still in motion here
- 11. the high point of a wave
- 12. the low point of a wave
Down
- 1. Wave particles of a medium move back and forth parallel to the direction the wave travels
- 3. The distance between one point on a wave to the same point on the next wave.
- 4. region of a longitudinal wave where the particles in the medium are closest together
- 5. at right angles
- 7. Wave the disturbance is perpendicular to the direction the wave travels
- 8. maximum distance a wave varies from its rest position
