مدى انتشار التفاعل الكهرومغناطيسي

الملخص EN

This research aimed to find the rang of the electromagnetic reaction.

It does that according to the theory of secondary photons, quantized time (T = 2πnћ/E), and the photon rest mass (mo = hH/2c2), and by calculating the range of the photon at this time its found that it is(T = 2c/H), and it is with full agreement with the result that found previously.
