Waves

4. wave A type of transverse wave that doesn’t need a medium (e.g., light, radio waves).
6. line The original, undisturbed position of particles.
9. The lowest point of a transverse wave.
10. One complete back-and-forth movement of a particle in a wave.
11. The material (like air, water, or solids) through which a wave travels.
12. The number of waves passing a point per second (measured in Hz).
14. The region in a longitudinal wave where particles are spread out.

1. The maximum distance a particle moves from the rest position (basically, wave “strength”).
2. The distance between two identical points in a wave (like crest to crest).
3. wave A wave where particles vibrate perpendicular to the direction of travel (e.g., light waves).
5. The highest point of a transverse wave.
7. A space with no matter; only certain waves (like electromagnetic ones) can travel here.
8. A wave where particles vibrate parallel to the direction of travel (e.g., sound waves).
13. A transfer of energy through space or a medium without transferring matter.
