- A photon is pure energy, zero mass.
- Different photons have different wave length and carry a different amount of energy.
Now, it seems logical that a high energy photon can be split into 2 low energy photons. I don't know if this could happen via some natural decay or under an external influence or not at all.
Please explain, thank you.
P.s. this is not a duplicate of the previous similar question about splitting a photon. The other question presents a photon as a particle, where as this one considers a photon as energy. I think this leads to different lines of thought.
