Each photon has a frequency and wavelength associated with it just as a wave in the wave theory had. However, each photon has a particular energy that depends on its frequency, given by the equation below. E = hf where: E = energy of the photon (J) f = frequency of the photon (Hz) h = Planck’s constant = 6.63 × 10-34 J s.
