Across
- 2. the lowest point before the rest position
- 4. motion any motion that repeats at regular time intervals
- 6. a disturbance in matter that carries energy from one place to another
- 8. wave a wave that travels along a surface separating two media
- 9. an area where the particles in the medium are spread out
- 11. the highest point of the wave above the rest position
Down
- 1. an area where the particles in the medium are spaced close together
- 3. a wave that causes the medium to vibrate at right angles to the direction in which the wave travels
- 5. the distance between a point on one wave and the same point on the next cycle of the wave
- 6. the material through which a wave travels
- 7. wave a wave in which the vibration of the medium is parallel to the direction the wave travels
- 10. the number of wave cycles in a given time
