I would like to propose an idea.
In quantum mechaics, the matter particle like an electron is seen to have dual nature, the one being particle nature, othe other being wave nature.
In physics, a photon is regarded as one species of elementary particle.
So a photon is a particle linguistically logically.
So a photon is a particle and, at the same time, is a wave.
That particle notion of the photon is a quantum of light.
Then what is the "wave" with which the above particle notion constitutes the dual nature?
And what is the equation that conditions the "wave"?
The "wave" is the original electromagnetic wave?
The equation the Maxwell's equations?
Thank you for reading, Sirs.
