We have seen in the previous chapter that the properties of refraction,
diffraction, and interference all require a wave picture of light. In this
chapter we will begin to study other aspects associated with light
which cannot be explained with a wave picture, but in fact need a particle
picture. The coexistence of phenomena which require both a wave and
a particle picture is called a wave-particle duality, and is at the heart of
the modern theory of quantum physics.
