  1. 1. The colors we can see on the electromagnetic spectrum
  2. 8. the power to make waves.
  3. 9. what kind of wave is a longitudinal wave?
  4. 10. what kind of wave is a transverse wave?
  5. 14. a logarithmic unit used to measure sound level.
  6. 15. when a wave goes through an object
  7. 17. a change in direction of waves when they bounce off a barrier
  8. 18. the process or action by which one thing absorbs or is absorbed by another.
  9. 20. the distance between identical points
  10. 22. the number of waves that pass a fixed point in unit time
  11. 23. motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance.
  12. 25. a vibration or disturbance transmitted through a material or through space.
Down
  1. 2. it is a kind of wave that is a sound wave
  2. 3. the opposite of a crest
  3. 4. a point on a surface wave where the displacement of the medium is at a maximum.
  4. 5. the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.
  5. 6. is the substance that carries a wave from one location to another.
  6. 7. the change in direction of a wave as it passes from one medium to another.
  7. 11. not transparent but clear enough to allow light to pass through.
  8. 12. The smallest ray on the electromagnetic spectrum with the most energy.
  9. 13. the spreading of waves around obstacles.
  10. 16. a wave that is an oscillation of matter and is responsible for the transfer of energy through a medium.
  11. 19. not able to be seen through; not transparent.
  12. 21. 1 of these is equal to 1 cycle per second, it has to do with frequency.
  13. 24. velocity of a wave.
