When the 'photon' is emitted, it would reason that the result of the energy fluctuation that creates 'it' rather is created as an energy wave, which when measured by us or a surface, it 'becomes' as a particle.
If my reasoning is right, the question then becomes why, or how, this wave appears as a corpuscular disturbance..
The more you know, the more complicated it will get, so I can see why knowing so little makes these questions easy for me to ask. I'm curious to see who is patient enough to educate a naiive question with a good natured 'schooling'.
