electricity , magnetism ,electrical field and magnetic field do not change the frequency of the photons.
If an electron of the matter collides with a photon the electron can be extracted by the matter and the energy and the frequency of the photon decreases (Compton effect)
I suppose it is the same thing with a positron ,but amm not sure due to the short life of positron

Shh!
Frequency of a wave, whether, sound or electromagnetic in nature, is an exclusive characteristic of the "material" that produces that. It therefore, never changes with external force fields or particles interacting with it. In fact, velocity and wavelength are affected by external world of different refractive indices or material world, but never the frequency.
You may read my detailed explanation to the question ""Does the velocity of sound dependent on amplitude" herein
