Quantic Optics

In all the articles before this chapter we have treated Light as a wave.  Although the wave theory of Light has explained many phenomenons and behaviours of Light, there are certain phenomenons that can’t be explained with this theory.  Because of this, it is necessary to “create” a new theory that can explain certain behaviours, for example, the photoelectric effect and the Compton effect, which aren’t explained in a satisfactory manner by the wave theory.

In the last century there have been great scientific and technical advances, many more than any other time throughout history, and this rhythm is accelerating as time passes.  In 1900, Planck’s discovery started research into the concepts of Relativity and quantum mechanics, which are now considered the two greatest theories of the twentieth century.  These theories have given us a new and completely different way of viewing why these phenomenon occur, and has opened our minds to new and extraordinary discoveries about the nature and behaviour of Light.
