Across
- 3. the lowest point, or valley, of a wave
- 5. the highest point, or peak, of a wave
- 7. the material through which a wave travels
- 9. distance from one crest to the next OR distance from one trough to the next ***careful with start and end point on this meaurement
- 12. wave appears to move forward; the direction of the wave is perpendicular to the direction of the disturbance; rope up and down, wave travels forward not up or down
- 13. a disturbance involving the transfer of energy from place to place
- 14. the distance from point of rest to crest OR distance from point of rest to trough
- 18. when two waves meet and cancel each other out (almost like colliding and causing them to stop)
- 19. wave has compression point that you can see move along the path of the wave; the wave travels in the same direction as the disturbance; spring/slinky stretched
Down
- 1. repeated back and forth or up and down motion
- 2. when two waves combine and the amplitude increases (more energy)
- 4. when a wave bounces back after hitting a barrier
- 6. ability to do work
- 8. wave waves that transfer energy through matter (something you can touch- the ground, water, rope, slinky)
- 9. a disturbance that transfers energy from one place to another
- 10. any substance through which a wave moves
- 11. the bending of a wave as it enters a new medium
- 15. s= λ• f (speed= wavelength • frequency)
- 16. how often a wave occurs within a given period of time (you actually COUNT the crests or troughs within a time)
- 17. the bending of a wave around an obstacle
