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