Across
  1. 3. the bending of a wave as it travels through a narrow opening or around a barrier
  2. 6. occurs when waves pass through a given point or medium
  3. 8. the bending of a wave as it moves from one medium to another
  4. 12. wave that only travels through matter like air or water
  5. 15. waves that can travel through matter or empty space
  6. 16. the maximum distance the particles of the medium move from their resting positions when a wave passes through
  7. 17. the material waves transfer energy through
  8. 19. the lowest point of the wave
Down
  1. 1. regular patterns of motion that can move through various materials and this disturbance transfers energy from one place to another
  2. 2. representations of actual images, sounds, words; usually use waves to transfer information
  3. 4. waves that are caused when the disturbance of medium is perpendicular (at 90° angles) to the direction of the motion
  4. 5. waves that are formed when the direction of the disturbance is the same as the direction of the wave
  5. 7. the distance from one point on a wave to the same point on the next wave
  6. 9. the information is converted into numbers (digits) using a binary code
  7. 10. the highest point of a wave
  8. 11. a language of only two letters - 0 and 1; a “one” represents the signal being one and a “zero” represents the signal being off
  9. 13. a measure of how many waves pass a fixed point in a certain length of time
  10. 14. when a wave hits a surface and bounces back in a different direction
  11. 16. when a wave’s energy is transferred to an object
  12. 18. unit of measurement for frequency
