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