Electromagnectic

Electromagnectic

1. Electromagnetic waves are the only waves that can travel through empty space

2. All electromagnetic waves are transverse and not mechanical(longitudinal)

   • Transverse waves are when the vibrations are perpendicular too the direction of travel

3. Gamma waves are the most energetic type of wave in the Electromagnetic Spectrum

4. The electromagnetic spectrum describes all the wavelengths of light.

5. When the heat is produced by the sun it travels to earth as electromagnetic waves. These waves can vary in their wavelenght

6. The range in waves lenght are from the longest on is over 100 kilometers long and the shortest is les that a billionth of a millimeter long

7. Electromagnectic waves travel at 300,000 kilometers per second

8. Ulturviolet waves are waves that are to short for the eye to see , they are very energetic

9. The short the wavelength the higher the frequency and the longer the wave length the lower the frequency

10. The high frequency waves are the most dangerous with Gamma being the most.
