Across
  1. 2. ultra-high frequencies that can travel through matter, damages cells (bone images, radiation therapy, production of superhero-HULK)
  2. 4. waves with low frequency (radio stations, microwaves, radar)
  3. 6. audio is sent by FM radio waves and video is sent by AM radio signals
  4. 10. converts electromagnetic waves into sound waves
  5. 11. electrical signals creates a radio wave that is transmitted to and form a microwave tower
  6. 12. waves made by vibrating electric charges and can travel through space
Down
  1. 1. system of satellites and ground stations that receive high frequency signals, amplify them and return them to earth
  2. 3. produces images you see on tv
  3. 5. waves that have a slightly higher frequency than radio waves (remote control, warmth of fire, satellites)
  4. 7. range of electromagnetic waves you can detect with your eyes
  5. 8. the entire range of electromagnetic wave frequencies
  6. 9. waves that have frequencies slightly higher than visible light (sunburns, Vit D production, fluorescent, materials absorb it, kills bacteria)
