Abstract

We write the charge-free Maxwell equations in a form analogous to that of the Dirac equation for a free electron. This allows us to apply to light some of the ideas developed for the relativistic theory of the electron. Valuable insight is gained, thereby, into the forms of the optical spin and orbital angular momenta.
