  1. 1. The amount of time it takes for a wave to complete one cycle.
  2. 5. A method of transmitting radio waves that can be used to broadcast high quality sound
  3. 7. The maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.
  4. 8. A common application of infrared.
  5. 10. EM spectrum with the longest wavelength.
  6. 11. A technology thst uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells. Your cells normally grow and divide to form new cells.
  7. 13. A technology that uses microwave radiation and allows devices to communicate with each other without cables or wires.
  8. 16. All bodies emit electromagnetic radiation over a range of wavelengths.
  9. 17. The number of waves that pass a point in a certain period of time.
  10. 18. A branch of medicine that uses imaging technology (usually EM spectrum)to diagnose and treat disease.
  11. 19. A wireless networking technology that uses radio waves to provide wireless high-speed Internet access.
  12. 20. One of the first 'professional' astronomers, and discovered infrared radiation

  1. 2. EM spectrum that is used in a digital thermometer.
  2. 3. EM spectrum that is used for satellite communications and cooking food.
  3. 4. This unit measures the number of wave cycles (or frequency) passing through a given point in a second.
  4. 6. The property by which light spread out according to its color as it passes through an object.
  5. 9. EM spectrum that can help find broken bones, tumors and foreign objects in the body.
  6. 12. The application of visible light to transmit data or signals.
  7. 14. EM spectrum that can cause sunburn.
  8. 15. EM spectrum with the highest frequency.
