Across
- 2. vibrations that produce an audible noise
- 5. the ability to do work
- 7. crowded areas of a longitudinal wave
- 10. repeating disturbance or movement that TRANSFERS ENERGY through matter or space.
- 14. wave travels from side to side, but the matter in the medium moves up and down
- 15. distance between any two successive identical parts of a wave
- 16. a space entirely devoid of matter
- 17. interference When two waves combine to decrease in amplitude
- 18. Bouncing of waves off of an obstacle
- 19. moving up and down or back and forth in a rhythmic way
- 20. Waves that don't need a medium to travel
- 22. wavelengths of light that are perceivable to the human eye
- 23. highest points of a transverse wave
Down
- 1. When two waves combine to increase in amplitude
- 3. Bending of waves around an obstacle
- 4. the matter in the medium moves back and forth in the same direction that the wave travels
- 6. number of full wavelengths that pass a point in a given time interval
- 8. Waves that can travel only through matter
- 9. stretched-out areas of a longitudinal wave
- 11. lowest part of a transverse wave
- 12. matter through which a wave travels
- 13. Bending of waves through an obstacle
- 21. greatest distance that the particles are displaced from their normal resting positions
