I have been desperately trying to find an equation (or a set of equations where I can derive an equation) that shows a relationship between the energy in an electric field and the wavelength or frequency of an electromagnetic wave.
I am trying to show a relationship between Wavelength and Intensity of an electromagnetic wave, and working backwards, the Intensity is proportional to the Energy Density of the wave, half of which is the electric energy density, which can be calculated by multiply the permittivity of free space with the energy in the electric field squared. But I can't find the equation for energy in the electric field (in relation to wavelength)! Any ideas?
