Across
- 1. The height of a wave from its resting point
- 7. the change in direction of a propagating wave (light or sound) when passing from one medium to another
- 9. forced vibration by another object
- 10. When two waves overlap and make a bigger wave
- 12. Time taken to complete one cycle
- 13. The emission of electrons from a metal when light shines on the metal
- 19. forcing something to vibrate
- 20. frequency that the object wishes to oscillate
Down
- 2. frequency shift due to motion
- 3. The length from one crest to the other
- 4. motion that repeats the cycles
- 5. high-low
- 6. How quickly a wave passes
- 8. speed How fast the wave was moving
- 11. The lowest point on a wave
- 14. wave a wave in which vibration of the medium is parallel to the direction the wave travels
- 15. The highest point on a wave
- 16. Occurs when an object causes a wave to change direction and bend around it
- 17. the bouncing back of a wave after it strikes a barrier
- 18. wave Displacement perpendicular to wave direction (ocean light)
