3 Electromagnetic Theory and Light
Light possesses both wave-particle manifestations.
Classical electrodynamics based on Maxwells electromagnetic theory unalterably leads to
the picture of a continuous transfer of energy by way of electromagnetic waves.
Quantum electrodynamics describes electromagnetic interaction and the transport of
energy in terms of massless elementary particles known as photons, which are localized
quanta of energy.
One of the basic tenets of quantum mechanics is that both light and material objects each
display both wave-particle properties.
In physical optics light is treated as an electromagnetic wave.
3.1 Maxwells equations
The simplest statement of Maxwells equations governs the behavior of the electric
and magnetic fields in free space.
Maxwells equations are generalization of experimental results.
