Are U sure that photons play a role in radio waves radiation ??
U sure?


Yep, radio waves and light are the same stuff (photons) just different
frequencies. They are all part of the electromagnetic spectrum that
extends from DC to gamma rays (and higher?)

Using particle physics to explain radiation from an antenna is easier to
understand than fields, waves, and Maxwell's equations. It allows us to
picture a tangible particle leaving the antenna. And lots of things are
understood about photons.

The RF energy from the source accelerates and decelerates free electrons.
The changing energy levels of the free electrons causes the excess energy
to be radiated as coherent photons.
