Proof That the Velocity of Photons Is Not Constant but Varies

It has been tried to prove: 1. Since the electrons possess spin motion, the photons emitted from the orbiting electrons too possess spin motion and their velocity depends upon frequency of their spin motion (ph w) and frequency of spin motion of the orbiting electrons (w); 2. The velocity of photons of infrared, visible, ultraviolet and higher frequency regions also depends upon their ph w. Their velocity varies as, e.g., an exponentially varying variable varies in very deep region of its asymptotic variation where the variation becomes extremely small but never attains any constant value. It has also been tried to prove that, when the electrons are accelerated by a large voltage, after attaining relativistic velocity by them as the rate of increase in their velocity starts decreasing, the rate of increase in their w starts increasing in order to conserve their spin angular momentum (s L), motional energy (m E) and motional momentum (m p). Because, due to their spin motion, they possess s L , m E = kinetic energy (k E) + spin energy (s E), and m p = linear momentum (lin p) + spin momentum (s p). The spin motion of electron generates tendency of linear motion and hence s p in it in the direction of its s L. Their mass does not start increasing in order to conserve their k E and lin p .
