Across
  1. 2. waves with some fixed points while the others between them vibrate with max amplitude
  2. 6. how fast a wave travels
  3. 7. symbol for wavelength
  4. 10. in a mass-spring system, this is where the force is zero and speed is at a maximum
  5. 12. point of complete destructive interference in a standing wave
  6. 13. the period of a pendulum is dependent on this (and acceleration due to gravity)
  7. 14. travels down a wave (but matter doesn't)
  8. 16. distance from one crest to the next
  9. 17. unit for frequency
  10. 19. period of an oscillating mass on a spring is dependent on this (and spring constant)
  11. 21. between nodes, where the wave has the largest amplitude
  12. 24. the combination of two overlapping waves
  13. 27. simple ____ motion is any vibration around an equilibrium position
  14. 28. potential energy is stored in a stretched or compressed spring
Down
  1. 1. wave type with vibrations perpendicular to wave motion
  2. 3. the maximum displacement of a wave from the equilibrium position (=the amount of energy transferred)
  3. 4. the physical environment through which a disturbance can travel
  4. 5. time it takes for one complete cycle of periodic motion
  5. 8. interference between two waves on opposite sides of equilibrium
  6. 9. lowest point on a wave
  7. 11. type of wave that requires a medium through which to travel
  8. 13. wave type with vibrations parallel to wave motion (stretches/compressions)
  9. 15. highest peak of a wave
  10. 18. number of complete cycles per second
  11. 20. a measure of the stiffness of a spring
  12. 22. additive interference of waves, amplitudes add
  13. 23. describes the proportional relationship between a spring force and displacement of a mass
  14. 25. this force brings a mass in a mass-spring system back to equilibrium
  15. 26. any decrease of the motion of an oscillating mass due to friction
