Electromagnetic Radiation

Electromagnetic Radiation

1. Light is a type of electromagnetic Radiation

   • Radiation is a transfer of energy
   • Visible light is radiation that eyes can fetect
   • Radiowaves > Microwaves > Infrared > Visible Light > UV > X-ray > Gamma

2. EM radiation transfers energy in 'Packets'

   • Energy is delivered as photons

3. Some types f EM Radiation transfer more energy than others

   • Not all photons have the same amount of energy > energy a photon carries is dependant on the frequency of the wave
   • The frequency and photon energy increases as you go along the EM spectrum
