WebWe consider the Weyl spinors u a nd v s eparately. The equation that a Weyl spinor satisfies is called the Weyl equation. Since the Weyl equation violates 1 W hen students see the Dirac equation for the first time, they might conclude that the spinors have 4 components because of the four-vectors seen in relativity. We can see here WebThis is the derivation of dirac relativistic wave equation,and the shortcoming of Klein gordan equation is described here.with this video i hope all your que...

The formalism of the RCQM is constructed on... WebCharge and the e.m. fields are introduced by adding extra-coordinates and then gauging the associated group symmetry. The resulting Dirac’s equation yields naturally to the correct gyromagnetic ratio ge= 2 for the electron, but differs from the one derived in the Standard Quantum Mechanics (SQM) in two respects.
