Title: Electromagnetic Waves


1
Electromagnetic Waves
  • What does energy have to do with waves?

2
What does energy have to do with the wave?
  • Electromagnetic wave A transverse wave that
    consists of changing electric and magnetic
    fields.

Electromagnetic wave
4
Electromagnetic wave fun facts
  • The energy transferred by this type of wave is
    electromagnetic radiation.

5
Electromagnetic wave fun facts
  • The energy transferred by this type of wave is
    electromagnetic radiation.
  • They travel at about 300,000,000 meters per
    second in a vacuum.

Electromagnetic wave parts from high energy to
low energy
  • Gamma rays

10
Electromagnetic wave parts from high energy to
low energy
  • Gamma rays Used to kill cancer cells (radiation
    therapy). Also used for precise surgeries (very
    small cuts).

11
Electromagnetic wave parts from high energy to
low energy
  • Gamma rays Used to kill cancer cells (radiation
    therapy). Also used for precise surgeries (very
    small cuts).
  • X-rays

12

  • X-rays Used to take pictures of bones.
  • Ultraviolet Low exposure helps your body produce
    Vitamin D. High exposure can cause sunburn or
    skin cancer.
