The Nature of Light
Light is natural phenomena that is said to have a dual nature because it behaves like waves (repeating fluctuations) and also behaves like particles (packets of energy).
The wave nature of light behaves like other kinds of waves, for example experiencing reflectance and interference like water waves, sound waves, etc. Light is considered to be electromagnetic waves (described by Maxwells equations).
The particle nature of light breaks light into streams of quantum packets of energy called photons. All light is an integer multiple of photons.
Light is always quantized, whether represented as a wave or a particle.
Polarization and interference phenomena are rationally described for light as an
electromagnetic wave, but not by quantum theory.
