Across
- 2. A disturbance caused by a vibration
- 5. A chemical reaction that gives off energy
- 12. The bouncing of waves (typically light) off a surface
- 13. Energy in the form of heat
- 14. The distance between one peak and the next on a wave
- 16. The number of cycles a wave completes in a period of time
- 18. A vibration that travels through a material, such as air or water
- 20. To take in matter or energy
- 21. Energy that does not need matter to travel
Down
- 1. A wave that occurs when the particles of a medium are displaced perpendicularly to the direction of the wave
- 3. The ability to do work or cause change
- 4. Height or "strength" of a wave
- 6. Energy that is stored
- 7. An area in which there is no matter
- 8. The bending of waves (typically light) as it passes from one medium to another
- 9. Energy that is not available to do work
- 10. Energy from motion and position
- 11. Energy of motion
- 15. Measurement of wave frequency
- 17. A chemical reaction that absorbs heat energy
- 19. A wave that occurs when particles of a medium move parallel to the direction of the wave
