Transformation of Orbital Angular Momentum and Spin Angular Momentum

The Lorentz transformation can be explained in two ways i.e. the special Lorentz transformation and most general Lorentz transformation. The length contraction, time dilation and velocity addition formulas for the special and most general Lorentz transformations are clearly explained. The variation of mass due to the relativistic velocity has also explained. Using above mentioned parameters we have derived the formulas of the transformation of orbital angular momentum and spin angular momentum for special Lorentz transformation. We have calculated the values of orbital angular momentum for rest and moving observers. The values of orbital angular momentum have plotted for the different velocities of the moving observers.
