  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. • http://www.google.com/imgres?imgurl=http://www.astronomynotes.com/light/emanim.gif&imgrefurl=http://www.astronomynotes.com/light/s3.htm&usg=__GVseWMb1yoPuB18VEHQWmqrsHdM=&h=311&w=496&sz=18&hl=en&start=1&zoom=1&um=1&itbs=1&tbnid=4YDWF2lJgNPfDM:&tbnh=82&tbnw=130&prev=/images%3Fq%3Delectromagnetic%2Bwaves%26um%3D1%26hl%3Den%26safe%3Dactive%26rls%3Dcom.microsoft:*%26tbs%3Disch:1&ei=tvyBTeLhC4i5tweO8IzJBA

  3. 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.

  6. 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. • Speed = wavelength X frequency

  7. 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. • Speed = wavelength X frequency • Wavelength decreases frequency increases.

  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. 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: Used to take “pictures” of bones.

  13. 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: Used to take “pictures” of bones. • Ultraviolet:

  14. 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: Used to take “pictures” of bones. • Ultraviolet: Low exposure helps your body produce Vitamin D. High exposure can cause sunburn or skin cancer.
