6.3 How is energy related to the wavelength of radiation

The energy associated with a single photon is given by E = h ν, where E is the energy (SI units of J), h is Planck's constant (h = 6.626 x 10 –34 J s), and ν is the frequency of the radiation (SI units of s –1 or Hertz, Hz) (see figure below). Frequency is related to wavelength by λ = c / ν, where c, the speed of light, is 2.998 x 10 8
