Light-ray bundle theory is extended to transmission through a refractive medium. The world velocity for a light particle is defined in terms of its trajectory, the world velocity of the medium through which it propagates, and the gradient of the phase function, with consideration given to the local index of refraction. Formulations are also developed for conditions of dilation and shear. The apparent speed of an electromagnetic wave is shown to be a function of the electric permittivity and the magnetic permeability of the medium. The analytical techniques are recommended for application to cases of optical or radio signals propagating through an intervening plasma atmosphere, and to radiation escaping from the accretion disk of a black hole, wherein lensing effects must be separated from the source properties.
