Electromagnetic Radiation (EMR)




Electromagnetic Radiation (EMR)

     Is a form of energy.
     It has a dual nature.
     Possesses properties of both discrete particles which are termed photons and of waves.
     Related by Planck equation
                                                               E = h v
                E : energy of a single photon
                V : frequency of the wave
                h : Planck’ constant (6.625 x 10-34) J.s
