  1. 3. The change in direction and wavelength when a wave moves from one medium to another
  2. 6. the highest point of a wave
  3. 7. the time between wave crests and is the inverse of the frequency
  4. 10. The measure of the displacement of the wave from its rest position
  5. 11. A wave that must travel through some sort of matter called a medium
  6. 13. the distance between two corresponding points on back-to-back cycles of a wave, for example, between two crests of a wave
  7. 15. a wave remains in the same medium, but bends around an obstacle
  8. 16. waves that can travel through a vacuum
  9. 18. The position is the position the medium would take if there were no wave
  10. 20. is the number of times per second that a wave cycles and is the inverse of the period.
  11. 21. a special type of electromagnetic wave that has a frequency in the visible spectrum.
  12. 22. a wave where the disturbance travels in the same direction as the wave like Sound waves
  13. 23. a measure of how fast the disturbance of the wave is moving and can be dependent on the type of medium that a wave is moving through
  14. 24. the lowest part of the wave and the opposite of the trough is the crest
  15. 25. A measurement of the strength of a sound wave that is equal to the power divided by the area
  16. 26. occurs when a wave bounces off a boundary, changing direction but remaining in the same medium
Down
  1. 1. the tendency for a system to oscillate with greater amplitude at some frequencies than at others
  2. 2. a wave where the disturbance moves perpendicular to the direction of the wave
  3. 4. is when a wave oscillates in one particular direction and are sometimes a special filter is used
  4. 5. the matter that a wave travels through
  5. 8. waves that are mechanical waves that are caused by a vibration and can be heard by our ears
  6. 9. a wave that remains in a constant position
  7. 10. when some of the wave's energy is taken away when a wave encounters a medium
  8. 12. Two waves when they have a constant phase difference between them
  9. 14. a traveling disturbance that moves through space and matter and transfer energy from one place to another, but not matter
  10. 17. is a number that describes how light travels through a specific medium
  11. 19. when one wave comes into contact with another wave.
