Across
- 3. when the path of a wave bends due to a change in wave speed
- 10. a vibration in matter that moves energy from one place to another
- 12. information is represented in a signal by this
- 13. the conversion of a wave’s energy into other forms of energy in the medium in which the wave is traveling
- 14. The matter in which a wave travels
- 15. any unwanted random signal
- 16. the distance over which the wave's shape repeat
Down
- 1. the maximum extent of a vibration or oscillation
- 2. waves made of vibrating electric and magnetic fields
- 4. when a wave bounces off the boundary
- 5. is a repeating disturbance that transfers energy from one place to another
- 6. a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves
- 7. a signal that contains analog information
- 8. anything that can transmit information
- 9. occurs when a wave travels across a boundary between media
- 11. a signal that contains digital information
