Across
- 4. the top of a wave
- 5. the height from the top of a wave to the middle
- 6. a wave with more frequency then visible light used mostly in hospitals
- 10. a wave going into a medium and transferring energy to it
- 13. a material that a wave can go though
- 14. the length between two crests
- 15. waves where the disturbance is perpendicular to the direction the wave is moving
- 17. a wave with less frequency then visible light used mostly in tv and radio
- 18. a type of fast moving wave with long amplitudes
- 19. this can be a partial or wave and can travel though a vacuum
- 20. the number of crests that pass a certain point in a amount of time
Down
- 1. the point where amplitude is measured
- 2. the bottom of a wave
- 3. were a material move in the direction as the wave
- 7. vibrating waves that can't go though vacuum
- 8. a wave bouncing of a surface
- 9. the length from the top of the wave to the bottom
- 11. a repeating pattern that transfers energy
- 12. when a wave goes though a different medium and the wave speed changes
- 16. the degree of highness or lowness of a tone.
