The Electromagnetic Spectrum

The Electromagnetic Spectrum

1. 7 different types of EM waves

   • Radio waves, Microwaves, Infra red, Visible light, Ultra violet, X-ray, Gamma Rays.
   • EM waves with different wave lengths have different properties.
   • As you go from Radio waves to gamma rays, the frequency increases and the wavelength decreases.
   • Different colours of visible light depend on the wavelength, e.g. red has the longest wavelength and violet has the shortest wavelength.

2. Uses

   • X-rays
   • Radio Waves
   • Infra-red
   • Ultra-violet
   • Visible Light
   • Gamma Rays
   • Microwaves

3. All electromagnetic waves are transverse waves
