- 3. The lowest point of a wave
- 5. The combination of two or more waves that result in one wave
- 9. A wave with oscillating electric and magnetic fields that move at the speed of light
- 10. The bouncing back of a wave when it meets a surface
- 11. The time it takes for a complete wave oscillation to occur
- 12. a pattern of vibration that simulates a wave that is standing still
- 13. the highest point of a wave
- 15. A wave that needs a medium to travel
- 16. The bending of waves as the pass from one medium to another
- 19. When two waves meet and cause an increased amplitude
Down
- 1. the maximum distance that the particles of a wave change from their rest position
- 2. When a crest and trough of seperate waves meet and level out equally
- 4. A wave in which the particles in the medium move perpendicular to the direction of the wave.
- 6. an observed change in the frequency of a wave when the source or observer is moving
- 7. A wave in which the particle move parallel to tho the direction of the wave
- 8. A change in the direction of a wave when it hits an obstacle or edge
- 14. The distance from a point to an identical point on a wave
- 17. the number of vibrations per unit of time; also the number of waves produced in a certain amount of time
- 18. A physical environment in which phenomena occur
