Across
- 3. the number of wavelengths that pass a point each second
- 6. a wave that makes the particles of a medium move back and forth parallel to the direction the wave travels
- 8. a wave that can travel through empty space or through matter
- 9. a wave in which the disturbance is perpendicular to the direction the wave travels
- 10. the change in direction of a wave as it changes speed, moving from one another
Down
- 1. the change in direction of a wave when it travels past the edge of an object or through an opening
- 2. the maximum distance a wave varies from its rest position
- 4. a wave that travels only through matter
- 5. a combination of a longitudinal and transverse waves
- 7. the distance between a point on one wave, such as the crest, and the same point on the next wave
