Re: What is a photon

This is MY DEFINITION of what a photon is, which merges Maxwell and
Planck:
A photon (Planck) is a ray of light (Maxwell), which is:
 - Self-propelled point-like particle that is the least component of
light itself.
 - It's a carrier of energy (Planck) that is emitted/absorbed by
electrons that
   are orbiting atoms, which have different levels of energy.
 - It's created as if space of any kind (Maxwell) IGNITES under such
discharge
   causing that the point-like energy oscillates with electric and
magnetic fields
   in quadrature, with speed depending on the refraction index of the
media.
- Under classic physics (Maxwell, unaware of Planck discovery) photons
are not
  perceived as a sum of enormous amounts of ray of light (each ray
linked to a
  bounded electron). On the opposite side, under Planck vision, light is
composed
  of a large amount of photons, each one with energy E=hf.
- The confusion between classic and quantum physics is due to the
interpretation
  of what light is. In Maxwell's world, light is the sum (coherent or
not) of huge
  amounts of ray of light (each one a photon), and is expressed in terms
of energy
  per unit area. In Planck's world, light is the sum (coherent or not)
of huge
  amount of photons, each one carrying energy E=hf.
- The speed of the photon or the ray of light is defined by Maxwell, in
terms of
  the permittivity and permeability of the medium. The collision of the
emitted
  energy per atom is what ignites the medium, creating the point-like
particle.
- The classic representation of light as a sinusoidal wave is just an
abstraction
  used for more than a century, representing the behavior of the
electrical field.
- There is not a dual behavior of light. This "paradox" is caused by the
confusion
  when light is analyzed entirely (Maxwell) or at its least expression
(Planck).
  Top-down versus bottom-up appreciation of light.
- But the point-like structure (the photon) has always been there since
1865-
Absolute truth has been spoken.
