The expression for the total energy of a photon is \(m_pc^2\), a sum of its linear KE and its KE in circular motion, BOTH at light speed \(c\). It is independent of its radius \(r\). The scheme above suggest that photon frequency can be increased by applying a current through a tapered coil. If photons are dipoles, we can also estimate the relative Left Handedness or Right Handedness of them as they occur naturally.
Have a nice day.
