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