photon momentum and energy is a frequent topic on the forum. consider a tardyon (u<c) the momentum of which transforms as(adsbygoogle = window.adsbygoogle || []).push({});

p=gp'(1+V/u') (1)

E=gE'(1+Vu'/c^2) (2)

state that special relativity theory ensures a smooth transition from the properties of the tardyon to the properties of a photon and make in (1) and (2) u=u'=c in order to obtain in its case

p(c)=gp'(c)(1+V/c) (3)

E(c)=gE'(c)(1+V/c) (4)

Is there more to say?
