Storyboard Text

  • Now you are gonna explain to your group,How is your wave useful?
  • Radio waves are useful because there used to radio convey information. Radio waves have from one place to another. longest wavelengths in the electromagnetic spectrum. Radio waves do more than just bring music to your radio. They also carry signals for your TV and phones. Thats how my wave is useful.
  • Ok so now you are going to discuus, How is your wave harmful?
  • Large doses of radio waves are believed to cause cancer, leukemia and other disorders. Some people claim that the very low-frequency- field from overhead power cables near their homes has affected their health, although this has not been reliably proven. Thats's how my wave is harmful.
  • Ok so now you are going to talk about, Can weather alter your wave?
  • However, rain hardly affects waves with long wavelengths (hf range and below.) You can assume, then, that as the wavelength becomes shorter with increases in frequency, precipitation has an increasingly important attenuation effect on radio waves.
