Across
- 2. the distance from one crest or trough to the other
- 4. increases amplitude when waves interact
- 9. a high point of a wave
- 10. how long or high you perceive a sound to be
- 11. distance from rest position to crest or trough
- 13. the apparent bending of waves around obstacles
- 16. the light beams will reflect at many different angles
- 18. a traveling oscillator that carries energy from one place to another
- 19. to separate into opposites
Down
- 1. the result of two or more waves over lapping
- 3. decreases amplitude when waves interact
- 5. a low point of a wave
- 6. the bending of a wave as it passes at an angle from one medium to the other
- 7. when an object vibrates at or near the resonant frequency of the second object
- 8. a solid, liquid or gas that is vibrated
- 12. it's the time it takes to move one cycle
- 14. the return of a wave as it hits a boundary
- 15. refers to how many cycles happen in one second
- 16. A change in the observed frequency of a wave, as of sound or light, occurring when the source and observer are in motion relative to each other
- 17. it equals frequency times wavelength
