Across
- 3. transfer energy from one place to another
- 4. The highest point on a wave
- 7. the vibrations are in the same direction as the motion of the wave
- 10. changes in speed of light/temp and densities of the same mediums
- 13. how fast the wave was moving
- 14. frequency shift due to motion
- 15. Frequency
- 16. the SI unit of frequency, equal to one cycle per second
- 17. the time that it takes to complete one complete cycle
- 19. The length from one crest to the other
- 20. The height of the wave
- 21. corresponds to frequency
Down
- 1. Return of a wave back to its original medium
- 2. a unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale
- 5. is a longitudinal wave and requires a medium to travel through
- 6. molecules far apart
- 8. the vibrations are perpendicular to the direction of motion of the wave
- 9. Molecules close together
- 11. The lowest point on a wave
- 12. Forced vibration by another object
- 18. How often or how quickly a wave passes by
