Summary
The geometric optics approximation to Maxwell equations is derived. The redshift and the description of bundles of rays via expansion, shear and rotation are defined. Equations of propagation of these optical tensors are derived. The proofs of the Goldberg - Sachs theorem and of the reciprocity theorem are presented. The equations of the Fermi - Walker transport and of the position drift of light sources are derived.
