- 10. 300000km/s
- 12. particles of medium move perpendicularly to the direction the wave is traveling.
- 13. material through which a wave travels
- 14. energy that doesn't require a medium
- 15. the number of times a wave passes a point in a given time
Down
- 1. distance between the troughs or crests of two adjacent waves
- 3. the height of a waves crest
- 4. energy caused by an objects vibrations.
- 6. powerful force that binds protons and neutrons together in the nucleus
- 8. attractive force that acts between any two objects
- 9. an observed change in frequency of a wave when the source or observer is moving
- 11. highest point of a transverse wave
