The Electromagnetic spectrum

The Electromagnetic spectrum

1. The electromagnetic spectrum is a continuous range of wavelengths.

   • The types of radiation that occur in different parts of the spectrum have different uses and dangers - depending on their wavelength and frequency

2. The order of electromagnetic waves in the spectrum- going anti-clockwise

   • Infrared
   • Visible light
   • Ultraviolet
   • X-ray
   • Microwaves
   • Radio waves
   • Gamma

3. Radio waves have the lowest frequencies and longest wavelengths, while gamma waves have the highest frequencies and shortest wavelengths.
